Agreed on the dually. We had a GMC 1500 that pulled our travel trailer for 3 years with no issues. It was probably the last RV we were going to own and didn't need a bigger TV; now we have the last RV we are going to own...maybe. However, once we decided to get a 5th wheel we went to the RV shows and such and started looking at weight. I decided to buy a truck that would pull just about anything by budget was going to let me buy, so I bought a GMC 3500HD diesel, CC, dually, long bed. Now that we have the Big Country I will never regret the decision. We pulled in 20-30 MPH cross wind about a month ago and it was not a problem, actually hard to tell the wind was blowing. I attribute that to the dual wheels and the extra stability they offer, not to mention it weighs about 8800#. Yes, I park it further from the mall door than my wife's car, but then I parked the 1/2 ton away from the door (dings) also. And I did have to learn that it takes at least two counties to make a U-turn. LOL! It is a beast, but we love it.
