Hello, I'm trying to find out wha's best to pull my boat and trailer with. I haven't had a problem pulling with either of my vehicles, but I'm trying to make the best choice as far as longevity. Should I pull with the vehicle with the highest torque or the highest HP if the tow capacity is not listed?

Why would tow capacity not be listed? Are you talking a new vehicle? If you search the older threads here, you'll find that tow capacity is a factor of much more than the HP or torque. It has to do with cooling (tranny and engine), tranny type, rearend gearing, wheelbase, braking ability, wt of tow vehicle and others. All mfr should give you 2 major capacities, Gross Vehicle Weight Rating (GVWR) which is how much weight can be loaded on the tow vehicle itself and Gross Combined Weight Rating (GCWR) which is how much the tow vehicle and towed trailer can weigh. Both include everything such as passengers, fuel, coolers, water toys, etc. To get your "real" tow capacity you take the GCWR and subtract the Gross Vehicle Weight or GVW (which mustn't exceed the GVWR).<br /><br />Specific to your HP vs torque question, the higher the torque, the easier it is to pull with. Little sports cars have high HP but not much torque while a big power stroke Ford has lots and lots of torque - hence they can pull heavy loads.<br /><br />BL...

Big He,<br /><br />Hotbyte said it all. Being able to get a load moving is one thing, being able to control it and stop it is another matter entirely.<br /><br />Every vehicle has a gross vehicle weight rating (GVW). Some have a GCW rating which is a gross combined weight. GCW means the difference of the weights of the tow vehicle and the load.<br /><br />Most manufacturers publish a trailer towing/RV guide which will tell you the GCW's of the vehicles and max. trailer weights. Don't buy anything without verifying you have the right equipment.<br /><br />To answer your first question, in a nutshell: torque gets the load moving, horsepower keeps it moving.

Since you stated they both tow okay, I would say it is your choice. I would personally base my choice between the two based on braking power and maintenance costs.<br /><br />Bob
