"Anyone use a residential fridge and dry camp?"

Yes, my 2015 Dynamax DX3-37RB is equipped with a 23 cubic foot, three door residential refrigerator. Said coach is a 39'3" "Super C Class" diesel puller that was equipped with two 12VDC house batteries. The dealer I bought it from lied and told me I should get about two days running said fridge on the batteries (via the 1800 watt inverter). I found I was lucky to see 12 HOURS before the batteries were depleted (and the instrumentation Dynamax included does NOT allow you to see how many amps you're drawing at any given moment). Last year, the Dynamax factory recommended Charger Enterprises (right across the street from the Dynamax factory) for warranty and upgrade work (where my enclosed car trailer was STOLEN). I had the two 12VDC house batteries removed and added SIX, 6VDC batteries (in a series / parallel configuration). I could then get two days without being hooked up to shore power (or need to run the onboard 8KW diesel generator or run the 350HP Cummins diesel engine). With the residential refrigerator, I could NOT find proper instructions for winterizing the residential appliances (the fridge has two ice makers and water on the door). Dynamax reps told me instructions were "on the Forest River website" but, all I could find were instructions for "standard" RV fridges. This season, I started having having trouble with the batteries NOT being charged by shore power OR the 8KW generator (they DO charge when I run the Cummins diesel engine). I've been back to the factory twice, had other issues repaired at the FROG Rally this past August but still, can NOT get GOOD answers to the many problems I've experienced. Everyone I've spoken with at Dynamax is friendly. What I need is COMPETENCE. Sadly, that seems to be in VERY short supply. So, the short answer to your question is that a residential refrigerator in the configuration as it leaves the factory, is NOT well suited for boondock camping. If you can add substantial energy storage (ie;more batteries), it can be made to work though.

Slap a few solar panels on your roof.
That would help a lot.
You already have the storage ( batteries)

Well, at 84 ah a day you'd need 3oo+ watts of panels on the roof and the SUN to keep up with just the fridge more if you want to run your other stuff...panels are a part time solution that may or may not fit and would still require the batts we discussed & and an alternate charging system for cloudy/shady/rainy days . The batteries existing are totally inadequate for such use.
a complete solar system is nice but with the big amp use, a 24x7 reliable system comes first IMO.

My comment was more at the dx3 guy.

With the 6, 6volts.

We have four 6 volt batteries and they will get down to about 50% in 8 hours. There's no way we would get two days out of them.

He was also limited by weight, and needed a bunkhouse being he has 4 small kids.
He searched all over the internet, and then went to the Hershey RV show. Great show and found a camper he liked. He ordered a 2016 vibe 308bhs. It's a beautiful TT. We go to pick it up last week and do the PDI. We find out that it has a residential fridge. Never would I have thought that we had to make sure it had a LP/electric fridge. Plus the actual dealer was from troy, NY. He picked it up from the Camping World by Hershey. Even though the guy was nice, he did not know much about this model. We were told each camping world has there own regional brands and they don't see alot of vibes go through there.
So the problem is that 90% of the time we dry camp on the beach. Having a fridge that only works on shore power or battery isn't going to work. We can run a generator from 9-1 and 5-9. But that still isn't going to work.
I told him to email Forest River and the dealer and see if they can work with him. We still are not sure if the residential fridge is standard equipment or an unwanted upgrade. Anyone use a residential fridge and dry camp?

What did his original paperwork say what it came with fridge. Did the one he saw at show have residential or domatic? I would have not taken delivery and made the selling dealer make it right and give you what you wanted. Just my opinion. I was not there so maybe not an option.

X2. Dry camping and residential fridges are not compatible. You could jump through exotic hoops to make it work,but realistically it's not going to be acceptable.

FYI I have 4 Trojan GC-2s, 480 watts of solar, and live in Arizona, with a Dometic electric/propane fridge, and I can just barely get by with that on electric. I only want to run the batteries down to 60% for reference.

You have the solar, wouldn't going to lithium batteries really help?

Right now, you can even use half of your ah.

Lithium can be taken down to 80% without and harm.

x3!
Since we primarily dry camp, we would never buy a RV with a residential fridge.
Too limiting and complicated.
Huge battery bank, large inverter, possible solar system required.
