I have 1,900 lbs of payload left in my truck for the family and I plus pin/tongue hitch ect. It scaled at 7,100 lbs no driver or passengers but with a full tank. 9,000 lbs gvwr. Would you go light weight 5th or tt? I was looking at the forest river ~25' bunk models and Trail lite and fleetwood has a short bunk. This would be weekends and vacation, not retired yet. Trying to move out of the pop top.
