If i had a family your size and your 150........
I would choose a non slide aluminum sided 26BH. If you pack light enough, your truck will handle it.
It will offer you, less weight than a slideout model with fiberglass sides and if you pack conservatively , manageable tongue weight which will be in the 900# range.
Remember, TW is distributed over all the axles with a WD hitch in use.
It offers you an island queen bed, sofa, dinette, bunks, and a bath large enough to get the job done.
This TT will roll down the road at 6500# or so , depending how you pack it.
If you read the Jayco owners forum, people who have this floorplan seem to be happy with the amount of room and storage it offers.
