The issue with a HD 150/1500 is they are still running the same frame that a true 150/1500 runs. Then factor in the cost of the up graded parts, six lug axles bigger springs and you are paying the same price for a lessor truck. The only reason I bought the Ecodiesel is for the fuel mileage and ride.
We no longer have a RV and do not plan on getting one until we are two to three years from retirement. Then it will be a smaller 7500# GVW trailer. In the mean time this truck tows my 6800# boat with ease and gets great mileage doing it. Plus it rides as good or close to my dads Caddy and that was out of his mouth!
If we decide to get into a larger trailer I will sell this and go back into a 2500. But at the cost of these new 150/1500 HD trucks I don't see me ever buying a want-to-be 2500. But then I said I would never own a short bed truck either so who knows.
