2010 Sierra Scotty HiLander

so i was avoiding this as I don't believe in suv's and mini trucks towing anything over  2000lbs, but I did have a tent trailer about the same weights (my second RV) and when I got it I had a 91 ford ranger with the big 4.0L in it.  so did it tow it, ya it did, but it was gutless in the mountians, didn't get good milage and so on.  a family situation caused me to need a bigger truck so we ended up going to a F150 with the 4.6L V8.  night and day.  it didn't even notice it behind it, got good fuel milage, flew up the mountan passes.  it basicly went from a ok experance to a relaxing one. 

 the difference will be frontal area, my tent trailer basicly had none this has a ton.  that is what will kill you at highway speeds and such, especialy if you have a head wind.   the curved section of the frontal area actualy makes it longer but offeres some wind smoothing, big formula for what I can see is not a lot of difference in the results.  the longer rear surface going so close to the ground is going to make more of a drag on the rv from the dead are space from the negitive pressure zone anyways.  I would just calculate it as full frontal area then get a truck that can handle that no problem. trust me it is a much more pleasent towing experiance if you are over trucked than if you are under.  I would look for somthing that the tow rating is 7000lbs or higher myself.
