I'm preparing to make a long trip and buying a travel trailer. It will be something a bit older like early 2000s and around 24ftish. I'd like to be able to have my dogs ride in the trailer while traveling. I know this controversial but I've weighed the benefits and risks and I'm ok with it. Also there's no where else for them to ride. Way to big to ride in the cab, and the reason for posting here too hot to ride in the bed with a camper shell. A big problem that I'm presented with is the heat. Is it possible, and safe to wire up an generator that would ride on the back to run the ac in the camper? I'd have it sit on one of those receiver hitch platforms. How much power do these really pull? I'd like to run the fridge too but that's optional. How long could I run off the house batteries? Im talking 2000 miles of driving most likely almoat non stop ( ill have multiple drivers) Maybe wire the batteries to charge off my truck battery? I did that with an winch on my car trailer.

You can't run the air conditioning at all on the batteries you can run it on the generator everybody does.

I am one of the few here that have actually set up a TT to do this. It CAN be done. But it won't be easy or cheap. And for most it won't be practical. If you cannot do the mods that are necessary yourself, it will be VERY expensive.

I installed a Onan Microquiet 4.0 using their underfloor mounting kit. I was wired with a ATF. I used about 45' of the thickest welding cable from it to the batteries. The genset was mounted just forward of the axles for best weight distribution. I installed a custom stainless steel 26 gallon gas tank for it. A fuel pressure regulator was used to prevent the carb from flooding from over pressure when climbing hills. A custom fire shield was installed.
All of this stuff required many hours of fabrication and a lot of welding.
It was a really slick setup, and was trouble free for over 1500 hours and many years until a lightening strike fried the genset.

I posted on threads about this with pics on this forum back then. If you are interested in more details, a search should turn it up.
It was before 2010, when I bought my present TT. I did not make this mod to it. Too much work, and the little Hondas do a fine job for me now.

In all practical theory, I see no reason why you could not run an air conditioner from a generator on your TT. After all, folks driving motor homes do this all the time. Their campers are equipped with the same air conditioners too. Figure out a safe and practical way to mount the generator and run the wire and it should work. Good luck!

You really need to think in terms of what is the ultimate extreme usage you'll be experiencing with your truck, not what is the lightest usage and hope it's OK when the extreme happens. - I quote myself.

It will work. But how will you know if there is a problem?

Can you just leave the roof vents open and a window cracked? I'm picturing a dog head sticking out of a trailer window. hahah

I have a dog and would not do it. What happens if the gen stops or ac trips? Will you know it? A dog stands a better chance with windows open that they can reach to breath out of.

I was wondering, why bother? After hooking up the water hook up the a/c and it will be cool in your rig while finishing up outside.

Not that big a deal to run a generator in the bed of a pickup with the trailer plugged into it while towing. Many have done it. Easy to monitor and dogs will be cool. Get a big enough generator. 3500 watts is a great match for the trailer you mentioned.

You might want to re-read the question.
