You'll also need to consider the terrain you'll be negotiating, and the weight and braking ability of your tow vehicle. Do you have trailer brakes? Towing somewhere flat as a pool table like Kansas and hauling the same weight down "Wolf Creek Pass" is going to require a very different tow vehicle, trailer, and brake setup. Getting moving, and "steering and stopping" safely is a whole different scenario. I had a friend who used to tow a 14 foot jon boat to his favorite fishing hole with his Harley Davidson motorcycle- - - - -at least until Officer Friendly wrote him a bunch of tickets, anyway!
