I am also looking at tha Jayco HT 5ers. It seems that there are two camps of 5er owners. One camp saying that a half ton can't pull them well and the other camp saying that thers's no problem. Since I don't own the unit yet and have not bought a truck yet, I'm in the investigative stage. The important thing is that I do not want to make a $30,000 mistake...and believe me I've made my share. Does a half ton get give better fuel economy towing than a three quarter ton? Or is the three quarter ton more fuel efficient?
A lot of question and a lot of opinions.
