If you turn off the propane valve to the main tank you can hook up any propane tank to the stay-a-while with the proper hose. This is what we do when boon docking. The easy way so you do not have to break camp to refill the propane.JasonWait! Is this a standard thing on U320's. And which valve is it in this photo? Quote Selected

Reply #27 – October 13, 2021, 05:19:28 pm The plug at the top is for high pressure propane if I need to run my generator.The valve at the bottom is low pressure propane, taken from a 40# DOT cylinder through a BBQ regulator and hose.See my pretty new POL fill valve and brand new vapor valve?

Correct, BUT many of us with propane generators converted from liquid LP to high pressure vapor-- hence the tap on the vapor line above the house regulator. In the photo, currently no hose connected to the generator from either port. No more clogged on-generator regulators. I converted mine 15 years ago after discussions and in person visits with an engineer at Marshall Gas-- then in San Marcos, TX. Quote Selected 2 Likes

No way for it to play!One of the things that gave us some concern was the single source of fuel for the generator. Now I'd rather handle low pressure propane after the regulator, but if necessary I can use a high pressure hose to connect my 40# tank to the system at the high pressure pipe plug and fuel the generator with vapor through the existing plumbing.The confusion over the supply to the generator comes from the high pressure vapor coming out the back of that high pressure quad fitting, looping over the tank and down to the dedicated regulator to the generator.See my pretty new POL fill valve and brand new vapor valve?

Re: How long for a Dometic Fridge to cool for food storage? Reply #33 – October 14, 2021, 07:17:09 pm Our Dometic refrig would take 24-48 hrs to get almost cold enough to put food into when we were getting ready to leave and then struggle to keep food cold enough for us. We had both internal and external fans and a fire suppression system. It was another reason we switched to a residential refrigerator with no regrets.Our Samsung refrigerator goes from a warm start to 38° in the refrigerator section and -2° in the freezer section in about 4 hrs.

Re: How long for a Dometic Fridge to cool for food storage? Reply #34 – October 15, 2021, 10:19:49 am Yeah ... when getting ready to leave for a trip, we would bring the coach to the house and plug it in to power. I would put one ice trays in the freezer, and it would take at least overnight for them to freeze. then I would monitor the fridge for the appropriate temps so I could transfer food. We also went to a residential fridge with NO regrets and much celebration ... and ICECREAM!!! Quote Selected 2 Likes
Re: How long for a Dometic Fridge to cool for food storage? Reply #35 – October 15, 2021, 11:30:02 am I run an extension cord directly to the fridge the day before we leave, set on #3 of 5 and the freezer is ready by sundown. I'll have a couple of frozen water bottles from the house and put them in the fridge to help the cooling.I have no idea how old the fridge is, it's a 3 way that I believe was replaced prior to our ownership (10yrs) Quote Selected

Reply #36 – October 15, 2021, 11:50:49 am The Dometic that was in my rig when I got it was cold in less than 12 hours andI gave it to my son for a off grid cabin and put in a residential fridge so now I don'tneed to worry whether the rig is level.

Re: How long for a Dometic Fridge to cool for food storage? Reply #37 – October 15, 2021, 04:25:09 pm Dometic RM 1282 cooling issuesSo IMO they will work BUT, i live in more of a extreme environment than most. Our new Amish cooling unit was 1700$ as i recall. It does keep food below 40 degrees and freezer in the 0-10 degree range when it hot out. 100+ is common for us. We also have a Serviceable Freon chiller for the freezer that works to minus 27 regularly when we choose to run it. 110ac. During our last trip i shut all the aux fans off once we were below 80 degrees outside. I did start fridge at a inside temperature of 100 and it took two days to cool off. It worked well for us during our trip and we brought fish and ice cream home with us. So i still haven't figured out acceptable out of level operating conditions. I did install a ARPFridge defend can genuinely see how they could be operated out of level on long climbs and descents but have yet to see any faults. I did actively turn it off for my daughters steep climb driveway. I'm sure we will eventually swap to a conventional fridge but like being able to us the gas till i have enough solar and batteries to operate. So it works for us BUT I still find myself checking it all the time. Also i use a external thermometer to check it without opening the doors. Currently operating with the thermistor at the warmer lower range and external setting at 3 from the last trip. I guess I'm getting more comfortable with it but still would prefer a Freon fridge better i thinkScott Quote Selected 1 Likes
Re: How long for a Dometic Fridge to cool for food storage? Reply #38 – October 15, 2021, 07:20:39 pm Scott, as I recall level of the Dometics is +/-3°. For a 36' coach that is about 11" between the front and rear axle. You can adjust 7-8" with air bags.Domestic says... "Thank you for contacting Dometic. The refrigerator should not be more than 3 degrees unlevel left to right, or 6 degrees unlevel front to back. We do not recommend having the unit unlevel for more than 1-2 hours as this can increase the chances of a blockage. However, we do recommend if you can, have the unit level at all times."Older refrigerators had tighter specs. Quote Selected
Re: How long for a Dometic Fridge to cool for food storage? Reply #39 – October 16, 2021, 09:47:33 am Living in the real world, and using not only "RV Style" refrigerators but also a Igloo propane fueled portable cooler since 1973:If the floor is level enough to walk on comfortably, the fridge is level enough to work.Dometic, Norcold and the Amish make ammonia absorption refrigerators and the world hasn't caught fire.All of the people using ammonia absoption refrigerators have not filled hospital emergency rooms with cases of food poisoning.I keep milk, eggs, cheese, vegetables and meat without abnormal spoilage and once again, the one thing we don't present ourselves with to medical professionals is food poisoning. Mayonaisse reaches its expiration date and more.And again, more level is better, but if the floor is level enough to be comfortable for you, the fridge will be happy. Quote Selected 1 Likes
