We have a Predator 5000W and it will run both A/C's. They are Furrion Chill Cube and amp draw is pretty low. I got a steel basket, mounted it on a 2' steel square tubing that fits the hitch and locked it in place with security chain/lock and keep it covered with bungee cords and tie down straps. Works great! Doesn't take up truck space, weight behind the axles and electric cord reaches R$V plug in without moving the generator. Don't use it often but it is a requirement when we go to Alaska,,,,someday!!!
Happy Glamping!!
Once upon a time I had a similar set up on the rear with a custom genbox to transport the generator it worked very well.
My next RV had a built in Onan Lp 5500. That set up took the genset operation to another level. Push button convenience though very expensive was superior to any portable set up. Lp power also was more reliable than gas and did not require gas cans.Transporting and hauling gas was not required.
Back when I carried my genset in a rear carrier dual fuel or Lp genset were not commonplace. However dual fuel lp powered genset are now readily available. The whole idea of carrying the genset on the rear and refilling with gas has less appeal now that lp genset are available.
I opted to get a smaller lp genset and simply keep it in basement storage.
I can get it out if needed. It's also always there in case of emergency unforeseen circumstances.
My current set up is sort of a compromise. I have the reliability of clean burning propane. No gas can s to haul or deal with. I am always self contained with A.C power available if needed. However I don't have the cost, convenience or unlimited power of a built in genset
