Beau,
It's very cool that you are getting a new trailer. I got the best price in town on a new unit from Trailer Source right there at Ward Road and I-70. You may have to order to get the best price though but the come in just a few weeks, A couple of things I learned from my trailer. Mine is a 12x7 and that is a lot of trailer to tow, if you go 10' or above make sure you go tandem axes with electric brakes otherwise your tow vehicle will suffer including tires.
Make sure when you build out your trailer you pay attention to tongue weight, especially if you have a single axle! Once again having an improper tongue weight will cause you lots of headaches. Oh yea and make sure you get 5/8" or 3/4" wall sheeting, 1/2" will be pretty tough to hang anything from.

No worries here I have all the power with the diesel dodge up front, and the handy exhaust brake. Bought a 12X6 with barn style doors and the side man door, all led lightning in and out. Ready to start rigging it up this week. Classic trailer sales had the best deal and great guys to work with.
