I have a 2000 Xplorer on a 1999 Dodge 1 Ton Chasse. The rig came with duallys. The ride is fantastic with none of the handling problems reported by Pleasure Way owners. It is a joy to drive. I believe the duallys make the big difference. Don't understand why Pleasure Way, or Roadtrek for that matter, didn't offer duallys as an option.
Our 99 PW has the one ton axel for dual wheels. I drive alot of one tons and I just new this was what I wanted to do to our new PW. so I did, I dont plan on adding weight, I did it for handling and stability only. the heavy axel that came on it is rated for 10,000 pound full floating axel. I did not do the duals for more GWV, I did it so the ride would be a pleasure,, and it is, I live in the foot hills and on curvy roads and unstable roads. The duals handle our mountain hilly roads with ease now. its like driving a completely different vehicle. However, I realize this is not for everyone, and that I was lucky my unit came with the proper axel and was a wide body. this would not be true for other units. I'm working on the fender flares now, I'll keep you posted on my DYI project on our PW
as near as we can tell it looks like about 1 mile to gallon, however, we would have to do more highway driving to really tell. But where we go fishing is more country roads, gravel, twisty curvey, so the mileage is way different than highway miles anyway.
Many Many years ago, I had a one tone dually dump truck and I snow plowed with it. I lived up by Streetsboro Ohio at that time and had plowing contracts with commercial parking lots. I did not have troubles with it back then.
But, I dont plan on using the PW in the winter,, So I really wont be able to say how it would or wouldnt handle in the snow because I dont plan on camping or fishing in the winter months.
