IMO, if you plan on towing lots of heavy loads (6,000 or above) you should get a v8, but really the 4R is not made to tow all the time so if you tow heavy loads frequently, get a full size pickup. SUVs like ours are very versitile vehicles and can tow lots of weight, but they are primarily cargo and passenger carrying vehicles with occasional or light (boats are easy to tow) towing in mind. Just my $0.02, not saying your in the wrong to tow a big camper accross country 4x per year.
