Good Day, the answer to your question depends on the weight of your trailer and the configuration of your tow vehicle. We have a 35' Grand Design that weighs 15k lbs, we started out with an F350 srw truck. It would pull it but we we very close to the 3700 lb payload rating of the truck so we purchased an F350 drw which has a 5500 lb payload rating to be safe. Better to be safe than sorry.
