We have two high top Nissan NVs, 8 cylinders, a NV2500 and NV3500. We don't know how we could spend a months at a time in a low top as we both have back and neck issues. It's nice to have eight cylinders.
The NV2500 is a 2017 with the 7 speed transmission and different torque on the engine and we can get up to 19mpg depending on wind and who's foot is on the gas pedal (mine is lighter).
The NV3500 is a 2016 with a 5 speed transmission and gets 14-16+mpg depending on wind and who's foot is on the gas pedal.
Yes, we love the vehicles. Hubby and I spent the first 1+ year full-timing, traveling separately, hence 2 vans. In the last year we've been traveling together in the 2500 and not using the 3500. That one has 72,000miles and 19months left on the original bumper-to-bumper warranty and is for sale...see down below at the Marketplace threads and on conversiontrader.com. We're at the RTR for anyone who's interested.
