Air hose reel mounting (split from Re: What did you do to your coach)

Mounted my air hose reel in the main compartment. The reel has 25' of hose on it. Did this to keep the friction loss down in case I happened to be using on of the impact wrenches. The 4 stainless mounting nuts/bolts do not go into the floor but have been counter sunk with the bolt heads up about 1/2". I went sideways into the step compartment to secure the 2x6" on the bottom and went into the step well on the top (see photo) to make it stable. I used a 1/2" spacer to keep the top reel mount away from the carpet and keep everything neet and square. The contractor's compressor can be seen in the background along with the big 1" air impact wrench. The air regulator and water separator can just be seen at the top of the photo.

The spare tire and surplus aircraft accumulator tank are in another photo. I welded a short nipple along with the quick connect on the tank to handle the large diameter hose in case I come across a lug nut that is difficult to take off. The tank can be taken to the wheel and the impact used on a short hose to minimize friction loss. I am going to replace one of the quick connects with a male air fitting and gate valve. I can charge the tank, remove the supply hose and take it anywhere I need air. Will air a tire or operate the 1/2" impact for 20 seconds or so.

"Flip" socket specs are shown it the last photo. This size should fit most all of our Foretravels with a 1 1/2" socket on one side and a 13/16" square drive at the other end. With the possibility of no cell service, I like to be prepared to change or air the tires.

A 6' pipe along with a bathroom scale are not shown but allow the breaker bar to remove any stuck lug nut. The bathroom scale is used to figure the torque when tightening the nuts. I do use a small amount of "no seize" on the studs and reduce the torque the recommended amount.

Cost: used compressor $50, new air jack $70 (on sale HF), 1/2" impact $40, 1" impact $95, used 60-70% Michelin from 2011 $80, Alcoa wheel $80 after selling 11R 22.5, Hose reel $49 at HF plus hoses, fittings, flip socket about $22, etc. 

Alcoa aluminum wheels are a terrific product, especially for the money. They are not cast like most automotive wheels but are forged like Porsche uses (but the Alcoas are a fraction of the price). In an accident, they WILL NOT break like a casting but just bend and are pound for pound much stronger. Big difference between castings and forgings. If buying one, check the model number to make sure it has the same offset. Wheels are available in polished or non-polished with different model numbers.

I have used the engine air compressor several times to use a 1/2" drive impact and even a die grinder. With the large air dryer,and all the receiver tanks it's a great system.Gam

Gam,

The OEM does work well for most anything but I didn't want to turn up the pressure regulator , didn't want to wait for the pressure to come up to 110 psi for the tires and most the time didn't want to start the main engine.

On the road with a flat tire, the engine compressor and impact will pop the lug nuts off without waiting for it to cycle much. The most that would have to be done is to slightly break them loose with a breaker bar first. A few drops of air tool oil in the air impact is as good as 20 psi more a lot of time.

All good points. For me on the road I always start with a check under the hood and leave the back open.Then start the engine and as it's warming up I go around  checking tire pressure as the air brake pressure is building.That way if I need air in a tire I can use the engine compressor. My compress Governor is set for 120 lbs and I never had any problems airing a tire.One more check of the engine for leaks or what ever,air pressure is up and I'm good to go.gam

Sounds pretty good. I could just connect my reel to the system quick connect a few inches away and air the tires while waiting in the morning like you do. Did you raise the compressor kick-in also 10 psi higher or leave it the same? Seems an idea to start putting air in before the compressor pops off. That way no waiting and the compressor never pops off while you are putting air in the tires.  Think I will give it a try.

My Governor cutout is set at 120psi and it resets at just over 100Psi. Newer systems come set as high as 130psi with the cut in set at 110psi Gam

Pierce,

Nice job. Looks like another upgrade/project for me and trip to Harbor Freight (yeah!)  I have a joey bed in mine and I would have to mount the reel higher on the step compartment to give it clearance.

Will your pancake compressor fill your tires quickly?  What is its max psi?  Is the air governor on your Detroit set at 110psi adjustable or the non adjustable type? Why not raise the cutout to 120 and the pressure regulator up also?

Here's an excellent video showing how one person can fill the tires with an air chuck similar to the one that Peter Fleming built. (Good job Peter and worth a Karma.)   

Airing up the tires with coach air

Here is a gadget I made that others might find useful. All the parts were purchased at a local Menards (similar to Home Depot) for approx $40. The coach air system cycles between approximately 85 to 120 psi. Trying to air up a tire that needs 90 - 100 psi is difficult when the coach air is on the low side, and the compressor hasn't kicked in yet. In fact, you can even lose tire pressure instead of adding pressure. With this device you can see where on the compressor cycle you are, and with the bleed valve you can release some air to get the compressor to kick in. Then, when the pressure is reaching the high end, start to fill the tire.

What do carry as a portable 12v compressor for day trips away from the coach in your Rav4?

Viair makes a 12v compressor specifically for rvs with a shutoff feature and 150psi.  VIAIR Corporation - 400P-Automatic RV Part No. 40047  Are you familiar with this one and do you think it could handle the load without burning up?  They are quite pricey and I am skeptical.

Thanks!  Good video too. Looks like the tire gauge wars are on. :D 

I have not checked to see if the cutout is adjustable but is on my to-do list. I bought the compressor to work around the coach, either for the tires or even for a HVLP spray gun. The big tank just gives a reserve for impacts or the spray gun so the pressure does not drop in the middle of a project. I wanted to avoid having to start the main engine. If we're dry camping, I have to start the generator but if plugged into shore power, it's nice to have the compressor come up to pressure and then shut off. It comes up to 125 pounds pretty quickly. Slower if I include the big tank. Only drawback is that is makes a bit of noise when running. The models with four feet are a lot more stable than the 3 footed variety. The rubber feet keep it in one place without fastening it down. For a lot of air, one could run the two in parallel.

I have almost the exact 12V compressor you link to in your post. I keep it under the seat in the RAV. It is in a much smaller black case and only has one yellow coiled line about 10' long. The ad you linked to is VERY optimistic. It will pump high pressure but takes a long time if any capacity at all is needed. Read great for a bicycle. The big problem is the 6 minute maximum they suggest. At the six minute mark it's almost too hot to touch the main body. I bought it at HF for about $40. Don't notice it under the seat and it's come in handy several times. Just not the thing to fill air mattresses or rafts with. From 25 psi to 45 psi on the RAV takes the full 6 minutes.

Here is the gauge I ordered to go on the double chuck: New in Box Weiss Instruments RG25 120 Pressure Gauge 30 0 120 PSI 1 8'' LM Gage found the outsourced pencil type was almost 10 psi off when filling the U300 tires. At 110 psi indicated, the actual pressure was close to 120 psi.

Pierce,

Okay,

Since we're talking about air compressors and filling tires are you familiar with this digital air gauge by Accutire model MS-5515B for trucks and rvs? Accutire MS-5515B Truck and RV Digital Tire Gauge with LED Light and Bleed  Not only is it digital, you can overfill a tire and then bleed it down without removing the gauge with the bleedoff button. Looks very accurate, easy to use and a real time saver.  Could be a must have for all of us.

Jerry,

I have a digital gauge in the center consul of the RAV. It works super well and rules 99% of the time. The 1% caught me with a dead battery in it. I'm just not organized enough to keep all the batteries changed in the coach on a regular basis. The video remotes seem to always be flashing "low battery" on the screen. I replaced the furnace thermostats with digital models a couple of years ago. They work slick but this winter was a close one with the rear furnace. I normally leave it set to 40 degrees to make sure I don't get anything frozen in the compartments below but one morning with the temps in the mid twenties, I found the rear heater off and the display blank. A battery change did the trick and I now keep a 16 pack of AA and AAA batteries in a drawer.

Distrust of wireless tire monitors and reading several complaints from owners who lost tires because of sender leakage have kept me from installing one of those systems. Plus, I know I would forget to change batteries.

How about a digital gauge that sits in an inductive charger/dock? An iPhone/Pad/Droid pressure module would be great. Probably around the corner.
