I just discovered FLR 5th wheels, what are your thoughts?

The outside storage is much less in the front living room floor plan also.

high pin weight, conplaints of loud acwhen watching tv, runs hotter upstairs, wall failures , less storage outside

I'm going to guess you mean Front Living Rooms? Are nice. May add a fair amount of weight to pin. Definitely need a 2nd A/C unit up there as it can get pretty warm (hot air rises). Able to sleep 4 up there pretty decently. Some brands have a better layout for the kitchen than others.
