Looking to buy a ightweight, modest travel trailer

Any of the 17BH models would work well.

Forest RIver has a Viking 17BH, which is a carbon copy (probably made in same factory) as the Coachmen Clipper 17BH.

My preference, get one with a roof A/C instead of one with a household, through-wall A/C.
The through-wall A/C seems like a place waiting fore a leak to happen.

ALso, look for models that have a side cargo door that opens in to the bunk area. That gives you a good opportunity for access to storage under the bunk.
