This is such good info! I am going to need to contact the Mfg. to find out what size wire is run of for the quick connect pre-wire. I actually think it is 10 gauge. Also, at this point I can't provide any real kind of load info since I don't have the trailer in my front yard yet. I am still speaking in the future plans. I mentioned 3 batteries at one time but that is what was in my old trailer. And also the dealer that made suggestions of adding the 85 to 150 and the fancy dancy reg/controller, I think he is legit. Yes he's a dealer, but I get a feel for folks and he's a do-er with his hands, not a brochure peddling fancy pants. I won't be able to use him as he is 6 hours away. We just went to his location because my wife and I wanted to see the trailer he had and we got a week end in Reno at the same time!
