thinking about getting a a frame popup made by forest river flagstaff just wondering if I would need a weight distribution system for this type of popup, according to the sale person dry weight 2700 l...
I am not sure the Aliner classic is a good comparison. The current Aliner Classic weighs about 1500lbs dry.
My 2016 Aliner Ranger 15 (larger box than the classic) actual dry weight is 1800.
Aliners are lighter than the FR's, so if weight is a concern and wants an A-frame (they're awesome for 2 people) than he may want to look in that direction.
You may also want to double check what the salesman quoted. He may be right, but in general, they're not always as smart as they think they are. ;)
