I tow a Carson 38' on floor Box with two stockers Wagon/1Dodge D150. I guess about 16,000 with 2,500 on Ball Hitch. I get between 10 and 12 MPG depending on terrain. With the air ride the tongue weight is no problem. I also have Vintage 53' gooseneck about 20,000 with 3500 on gooseneck.I haven't gone far enough to check MPG but I can't tell much difference! The reason there is not a pass thru is it is a 5 passenger cab and back bench converts to bed, However it would be easy to put a rubber camper boot between cab and box. I did that on last Kodiak Truck.... no big deal. I really like to sell this ... Vintage has living quarters. My equity line I bought it on is down to $49,812. I'd take that....Registered as Moterhome in Nevada cheap to insure and no sales tax if you want to continue to reg in Nevada
