Well, honestly, I travelled all over BC, Texas, Alaska, east to Newfoundland, many trips to Arizona, all with camper on 2 w/d truck, and never an issue. Drove in snow at times too.....however, this was never off road travel....When I bought a trailer I decided I might need 4x4 just for backing into some soft ground camping spots, or towing in snow if I got caught getting over a pass....this proved to be a good thing as 4x4 did save my butt a couple of times with the trailer.....now I into a camper again with 4x4 truck and honestly, only use it for climbing up onto blocks when leveling at camping spot.
