Nissan camper van or tow vehicle.
I own the Nissan NV 2500 high roof model and love it. I use it as a tow vehicle for a small travel trailer. The mileage difference while towing is not much different (maybe 2 mpg less). I have had zero mechanical problems in the 6 years I have owned this vehicle and have 86, 000 miles on it. I often am asked questions at gas stations etc. about head room etc. it draws much interest. Have also used this vehicle as a camper van prior to buying a trailer. Lots of space to camp in.
