Hello, I am new I and wanted to ask if anyone out there is utilizing a 2WD 2500 Cummins Crew Cab to tow their travel trailers / 5th wheel. If so, do you regret not purchasing a 4X4 ? I have an opportunity to purchase a 2010 2WD 2500 Crew cab with 78000 miles. I am still in the market for a travel trailer. I am not sure if the 2WD will be sufficient. I Do not plan on going into a extreme weather conditions or non-pavement roads if it is possible. I would appreciate any feedback that anyone can provide. Thank you
