Having just gone through this and ending up buying a trailer larger than some people live in... here's what we can tell you.
Rule Number 1 - the trailer and everything in it will weigh far more than you expect. OVERESTIMATE. Traditional wood and steel trailers are HEAVY and may end up weighing too much for your Durango. Check out Featherlite - more money - but they do hold their value and weigh far less.
Rule number 2 - goes with rule number one... You can never have too much tow vehicle. You do not want to struggle going up hills or pulling away from a stoplight. You also want to make sure you can STOP the darn thing.
A couple other things to consider... the side door is nice, but most trailers do not have low enough wheel wells to make this work. Ramp overs solve that, but then raise the weight in the trailer making it less stable. Get the widest trailer possible. It is possible to climb in and out the window. We have a winch and don't use it yet.
Aluminum treadplate floor is NICE. Helps the car grip, easy to clean, non -slippery when wet. Checkerboard looks nice in the beginning - that's it.
Ramps - most will not allow you to drive into the trailer without modification. Our featherlight has a fold down door *** 6 foot ramps. Car drives right on without having to use 2X10s or some other hodge podge of stuff.
Get the weight distributing hitch.
Get the tie downs form Snappin Turtle with the proper frame hooks so you will not damage your frame. 1 800 TIE DOWN. BEWARE - the nose of your car is VERY LOW and most traditional tie down rings will not work. We use 6 d-rings per car and use one set to run the tie down THROUGH - that pulls the car down and the tie does not touch the fascia.
OK, this is getting too long. Email me or
