Totally agree with the post that said, it will depend on how you are going to use your RV. While we were still working we had a 38' gas MH. I really wanted a DP, but could not justify the cost for the amount of time we used it. It was great for two week vacations and going to Gator football weekends. Once we retired and planned on going full time the biggest DP we could find would work for us. We ended up with a 43' Newmar Dutch Star. We love it. First it is a quality MH. We have plenty of power. 2 stage engine brake for the mountains. Tons of storage, inside and out. For us, this was the only way to go.
