I just purchased a 2000 Gulfstream Conquest Class "C" motorhome. It has the Ford E450 Triton V10. Gas

I am wanting to get a vehicle to tow and am leaning towards a smaller High milage 4WD SUV.

I would like some opinions on vehicles to consider and why, also whether to tow trailer, dolly , or 4down. At this time I am hearing more good things about towing 4down.

Thank for any words of wisdom since this is my first RV and also I am not very mechanical.
