I just bought a Sundance 310QB which is the same trailer except for the decals. I have a quad cab dodge 1500 with just a 4.7 V-8. I pulled it across the mountains of Virginia and east Tennessee with no problem. I agree it didn't pull like a 3/4 ton truck would, and will probably upgrade in a couple of years as my mileage reaches 100k, but it did fine. It actually pulled the new TT better than it did my 24ft. TT I had that only weighed 4200#. You are not going to be able to go 65 - 70 MPH in mountainous areas and your gas mileage will suffer some. I checked my mileage coming back from a trip to Gatlinburg, Tn to north central Alabama and I still got 10 MPG in average road conditions ( not overly hilly). Your truck would be fine it just might take you longer to get where your going. Mine drives and pulls nice and level with the WDH and turns about 2300 RPM at 60 MPH on the interstate. Good Luck. If you choose this floorplan you will love it. Get the A/C upgrade to the 15k BTU though. I'm glad I did.
