Tow Vehicle
4 Wheel is nice to have getting up ramps but unless you live in snow country or travel back country roads, 2 wheel with limited slip rear end is sufficient. What is more important in towing are knowing the Vehicle Gross Vehicle Weight Rating (GVWR), Gross Trailer Weight Rating (GTWR), Gross Combined Weight Rating (GCWR), Gross Trailer Weight (GTW) and Tongue Weight (TW).
