I am on my second toy hauler which has done quite well but it is only 21 ft. and we are thinking of updating to one with a metal frame, ours is wood, and figured one between 24 and 28 ft. would be about right. It would need at least a 30 gallon fueling station and a 4k generator. We don't dry camp a lot but 75 gallon fresh water would be nice. We are thinking something between 1 and 5 years old. Any help is appreciated.
