Thanks for all the ideas. Now I have a new project.

All these sound good, but what happens when you want to take you truck when you are hooked up? I would worry about bad weather with the batteries in the back of the truck and storing them when moving. I hook the extra batteries in my trailer when I leave home and take them out when I get home. Good luck

I have occasionally had the same need. I bought a pair of jumper cables, took the clamps off of one end and wired the ends to the appropriate terminals on a 7-way receptacle. The batteries stay in the back of the truck (backed up near the fiver) and I just plug the trailer plug into the end of the jumper cables. I have plenty of batteries around the farm that I can "borrow" for the rare weekend that we dry camp.

These are batteries I used in my boat for a trolling motor. They are in plastic boxes with vented covers on them. The vented covers will keep out most water. If I am not hooked up to them I will still have the single battery in the trailer to operate it. Just trying to get more power for the occasional night I may have to land in a Wal-Mart or such for a few hours of sleep. I use a C-Pap which I can run off an inverter and don't want to run out of power.
You have a pretty sizable trailer. I wouldn't worry about weight. I have 400 lbs of batteries in my 9500 lb GVWR trailer and I'm still 1000 lbs under GVWR. I would permanently mount those extra batteries. WAY less hassle.
