Who to believe?

6 months will defiantly drain the battery to nothing.. my radio and co detectors are powered with the battery hooked up. a week or two and its dead.. one of these days i'll put a disconnect switch on it.. maybe this summer...

take the battery out and put it in the house on a battery tender while you are away

and yes 15k is cheap for a new travel trailer so yea i'm sure it will wear quick like stated..

so what did ya buy? last year i bought a 2017 bullet crossfire 2070BH. only been out in it once.
