Our 38' Newmar 3 slides has a 6,000 lb tow capacity and it is on 22.5 wheels. The V-10 with the 5 speed Tow Haul transmission does a great job of towing our Jeep. Very seldom do we know it is attached (check in the rear view camera occasionally to make sure) We have been in 40 states and across the western mountain range from north to south numerous times and do not remember being passed by any 18 wheeler except those running empty or the 500 + HP.. All slow down of the steep grades. The V-10 is an excellent engine and develops more HP (362) than most diesels in similar size coaches. The overall average fuel MPG is 6.
Newmar builds quality coaches and the insulation is excellent, masking most of the engine noise.
