Engine hatch changes by extreme- advantage?

I noticed some U320 owners have had engine hatch redesigned by Extreme
 

Is there a thread that explains advantages to doing so?  (Or comments).

Does it change ladder access to roof?

Dan,

Rance at Extreme is an experienced expert at getting rid of the very heavy engine door.  Eliminates door falling on the back of a worker and the strength needed to lift the original door.

Rance splits the door with the bottom foot or so separated so it can stay on coach when the upper part is opened.  This also has the advantage of never having to adjust hitch when opening door.

The upper part can be split vertically with side hinged.  We chose the other mod where our upper part is one-piece and hinged on the top and held up with air struts.  Also the door was also made lighter by removing inside material that was needed to support the original structure.

One of the best mods we have made.

Many years before changing our engine door, we always used an aluminum "A" ladder bungeed to rear ladder so we did not have to rely on the questionable strength of the ladder fasteners.  We climbed our "A" ladder as high as we could before transferring to upper RV ladder to climb to the roof.  When we painted 5 years ago, the original ladder was removed with everything else, and to our surprise almost all of the ladder's steel grab-fasteners located inside the ladder were rusted, so we were correct in using our "A" ladder.  Only a few fasteners supported our weight when on the ladder steps.

That being said, when our door was split and hinged, the bottom half of the roof ladder was permanently removed, mainly due to the  lighter door and conflict with upper hinging.  We now have to use our "A" ladder to reach the reinstalled (with new grab-inserts) upper ladder.  So nothing has changed for our regular climbs to the roof to access roof pod, clean roof and solar panels.

And it reduces the attraction of a stranger wanting to climb to the roof.

Barry and Cindy covered it pretty well, and we had the same reason for the conversion

1)  You don't have to move the tow bar to open the rear hatch.  The original interfered with our KarGard II tow protector even after we added an extension to the towbar shank so we couldn't open the engine bay with the car attached (and had to drop the tow bar from the stowed position when it wasn't)  We always worried about a tech not knowing this and damaging the door trying to open or close it, so we always took the tow bar off when we went in for service.

2)  No worries about heavy door being properly latch above your head/back when working on the coach

3)  Reduced weight makes it easier to deal with the door

Lower ladder is removed; we use our stepladder to get onto the upper portion.

Lower position is pinned into place and comes out (I think it tilts out of the way; I wasn't at the back of the coach when Steve and Rance went over all the details) so you can access the lower things like the air dryer.  Fluid checks, adds, and many maintenance items can be done with just the upper part open.

When we had our conversion done (this past April), Xtreme indicated they prefer not to do the vertical split, open to the side style doors anymore.  I believe this is because you need more room to swing the doors open, plus the hinges are under more stress.  I think ours was the first 02-05 done since Rance had to do some prototyping to get the pivot point just right for the upper part.

Cost ?

Our quote was 40 hours plus $400 in materials. 

Our actual bill has a bunch of other stuff on it (like our side cameras), but figure around $4600 plus tax for just the engine bay conversion.

I saw a pic of Michelle & Steve's conversion, to kill for!  Our GV is just as bad for acess + the dweeb latching door has "trash me" written all over it!

This is the conversion that James at Extreme did when he owned our coach.  Note the missing ladder.  He hates them as I believe he fell off one once.  We use a separate ladder, much safer than the flimsy originals.

What type of " separate ladder " would that be that safely goes to the top of the coach and still stores below. My guess is a collapsing ladder ?

Well, I for one will speak up for the original status quo. I don't mind the hatch at all. It takes just a little bit of muscle to raise and when full up, it is so far over center that I have a hard time imagining anything but gale force gusts of wind or major earthquake causing it to drop unexpectedly. A couple of well placed bungie cords can drop that to a near zero chance easily. Clearance issues with a tow bar is a consideration for many. We have an extension with minimal drop to accommodate a bike rack that makes the normal tow bar stowed position unworkable, so when the toad is unhooked and tow bar is on coach, I just strap the towbar to the horizontal part of the bike rack. I can open the hatch far enough with the bikes on to check the coolant overflow bottle level, and can open the hatch all the way by removing the bikes. I am not saying that the original design is superior to the Xtreme modification, just that I haven't found it to be a bothersome issue. At least not one worth $5K :o
Edit: I like having the ladder there. I just replaced some of the standoffs on the upper portion. Modified the lower portion long ago to eliminate the rusting star nut problem.

I agree. So far, at least, I have seen no reason to consider changing the design.

Robert,

We tried a folding ladder that proved heavy and cumbersome to use so we got a 3 section extension ladder at Home Depot.  I put some foam pipe insulation over it where it rests on the coach to protect the finish and stop it slipping.  As it projects above the roof it's easy to get on & off of.

Little Giant folding ladder is what I use on my current coach.  It is heavy, but super strong.  Works as extension ladder, or as A frame ladder.

There are also paint protectors available for the ladder edges to rest against the coach.

Here is one in following link.  I have a better product for that, but can't find it on the net right now.

Agree with Don, hatch seems to cam over at full extension and take quite a bit of force to un cam. then lowers about half way before having to push it down. Also I don't understand the issue with the factory ladder set up, mine feels very secure as long as the hatch is locked down before climbing.

I'm of the same mind as Don and Craneman.

Don,
 
I backed into something on the way home from purchasing our Foretravel a couple of years ago. I removed all of the bottom section except the standoff locations. Those star nuts seem to be rusted through and I have a hard time getting a grip on them to unscrew them.
 
What was your secret to removing yours (maybe no rust)? Maybe it's a two-person job and I need to get Jean involved.
 
Any assistance or advice appreciated.
 
Thanks,

Trent

I wonder if the coaches came with the 3 piece rear door if extreme would be modifying to a one piece.

As I understand it, the original engine door conversion came about because an owner didn't realize the door hadn't latched and it came down on his back as he was checking fluids.

Also I don't understand the issue with the factory ladder set up,

Factory ladder is rated at something like 225 lbs or slightly under  If you look at the structure, the climber's weight is actually being borne solely by the screws that hold the plastic rung ends in.

As with anything, it comes down to personal preference and what projects are important to you.  We had our conversion done for us, not anyone else, and it saddens me to read the negative comments directed at someone's choice of upgrades for their coach.
