We are tossing around the idea of ditching our toy hauler and going the traditional 5th wheel route. Some of the 5th wheels we are interested in only seem to be offered with residential refrigerators. Will this pose a problem with camping without hookups, which we frequently do? We've only ever had RV refrigerators that can run either with the generator or propane.

We have the Honda 2000 at the cottage in case of power outage.
It keeps a full size fridge going no problem as well as the Satellite & TV and floor lamp.

If you have an adequate solar system and batteries with a small generator backup, you’ll be fine.

Our plan is to have a model with a built in generator like we have now [emoticon] But one trip we do every year is in a hotter climate, so we need to be able to run 2 ACs and the refrigerator at once. We do not NEED a residential refrigerator, but some don't seem to have an option to not have one.

A modern residential refrigerator doesn't use a tremendous amout of electrical energy (though the startup surge can be pretty substantial, hence the need for a decent sized inverter if running off of battery power). The typical energy star stickers I've seen are around 1 kWh per day. Provided you have a way of getting that much power into your batteries, and the battery bank is reasonably sized, you won't have any problems at all. For many people perhaps 200W or so of solar power would suffice under most circumstances, though of course that depends on where you're setting up camp. In the woods, shaded by trees, solar is not so effective!

In short, the answer is that it most likely needn't pose a problem, but you do have to make adequate preparations (or check for adequate equipment) to make sure that's the case. Not a few fifth wheels are set up from the factory with the assumption that the owners will not generally camp without electric hookups.

It depends on how long you want to run the frig without shore power. A typical new 18 cu. ft. residential frig can draw 30 DC amps from the batteries during its on cycle (cycling depends on installation, insulation, ambient temps, how often the doors are opened, etc.). I just had a conversation with an engineer at Battle Born Batteries about our new fifth wheel that's on order. With a residential frig, he recommends two 100 amp hour LiPO4 batteries and 300 - 400 watts of solar for anything longer than just travel days. Without solar, you would need a generator as mentioned above running a couple of hours every day to keep things charged. Also bear in mind that you can't draw lead-acid ("flooded") batteries nearly as low as lithium ion batteries - and LA batteries' voltage drops off as they drain.

As mentioned, we will buy a 5er that can have a built-in 5500 Onan (our current rig has this and we do not want to give up any amenities we currently have). We don't plan on having a solar set up since we will have the generator.

When we boondock, it's usually for 4-7 days. As an example of a use case, one trip is 5 days, at a music festival where it can get close to 100 degrees or above during the day, so we run the generator pretty much all day, and turn it off when we go to the shows around 5pm. We might run the generator a little after we get back around midnight so we can run the AC if the camper feels warm, but we turn it off before we go to bed.

My main concern is if a built-in 5500 generator is enough to power a residential fridge, and both ACs, all at the same time. We aren't worried about running the TV or anything else with a heavy draw at the same time, and basically, the only time the generator is off is when we aren't in the camper or are asleep (so the battery would only need to power the fridge during these times).

YOu should be able to order either a standard RV type absorption or.. If you google carefully both Dometic and Norcold at one time made what I call Danfoss class Refrigerators.. (NOTE Danfoss is ONE of at least 3 different compressor designs) Engel makes some Chest Style refrigerators (Top lid) and at least one model can hit 3.6 Degrees (Freezer) if you ask it to (That model is against my left leg as I type which is how I know) they call the compressor a "Sling compressor" about 40 watts.. That's about the same as a dual 1141 light fixture.

They cool slow. but they do work and as I said Dometic and Norcold do sell chest style units in that design but they also made at one time Upright models.. Do not know if they still do.. Very nice.

And remember.... If you are ordering NEW. they give you what you want or they see your backside walking out the door with a blank line where the contract says "Buyer's signature" and to a salesman that is a BIG problem. in fact it is the ONLY problem.

“We don't plan on having a solar set up since we will have the generator.“

No solar “set up” since on many days that would eliminate the need to run a generator and this new fangled solar stuff is still experimental anyways? No, it’s not experimental. No, it’s not new fangled. No, you like the sound of generators?
