Running a/c off generator while towing

My AC cools the trailer while I am setting it up (10 minutes).

I had a cage made up to hold the generator. It is welded to the main frame.

How are you going to plug the trailer into the generator? Does your trailer cord go out the front of the TT? Is your generator a built in unit? I would worry about the cord being pulled out of trailer if you have the generator mounted outside the camper or in the truck bed.

I was going to mount generator in the back on the bumper, closer to cord, if it will work ?????

Rear trailer bumpers are not built to carry any weight. Have seen more than enough torn off just from bike carriers or spare tires due to very thin material the bumper is made out of. A place to keep sewer hose is about all they were built to handle.

Thanks for the input

If you can mount the generator safely then yes that would be great.

Not just the generator but the cord also (not so much of an issue with a built in generator)

If traveling in really hot weather, we just open everything up to flush out the hot air. Assuming it's not rainy or dusty, doing it 10-15min before arrival then driving will be even better. Then turn on the air/con.

This is where the MaxxAir vent covers come in handy, we set the bedroom to suck in and the bathroom is always exhaust so just turn those on and I can have it down to ambient in about an hour, rain or shine.

Vent covers are on my To-Do list. Had them on prior rigs. Then yes, just leave them open a bit before even hooking up.

You can securely wire tie the cord (or an extension cord) under the trailer right to the trailer tongue. Then just like your 7 pin trailer cord leave some slack and loop to the vehicle and run to your gen.

Myself, My shore cord uses a hatch with a mouse flap, it is big enough to get my hand inside the door..

So.. I mounted a 30A socket INSIDE the hatch, ran 10/2 with ground Romex inside the trailer up to the tongue and terminated that to a 15A/20A plug. Now I can run a short 12/3 extension cord from the gen in the truck bed to the plug on the tongue for a quick way to power the trailer at any rest stop I want power..

That setup also does double duty when I stop at any relatives home for a day or two for plugging into their outdoor 15A/20A outlets without pulling the 30A shore cord out..

As far as running the gen while driving, never tried that. I have a cover on my truck bed so have to open the cover to run the gen..

In theory, it could work although I vaguely remember some posts yrs ago that some folks had issues keeping their portable gen running.. Might have to do with the gen not protected from high speed winds and or vacuum created when driving..

Myself, just start the gen when we stop and run the A/C for 10 - 20 minutes is enough time to take the edge off of the heat buildup, works pretty well for us even in 90F+ temps.

wouldn,t the cold air get sucked out?

Do you travel with all your trailer windows open?? In truth trailers are pretty tight. In winter when traveling in cold weather we run the furnace when traveling so the rig isn’t an ice box when we arrive. It is toasty warm when we open the door.
