[Carl n Susan]

I had a 2WD originally. The only advantage is the SRW models have a 2" block on the axles v. the 4" one on a 4WD model. Consequently, the truck sits lower and the RV isn't nose high.

But having gotten stuck 3 times backing over my lawn to store my RV in the back yard (and several other times) convinced my wife a 4WD was needed. I don't use it often, but when I do it keeps me from being stuck.
