On the trailer thing
There are a couple of trailer places down near me (but thats in AL) so might not be in your shopping zone. Lone Wolf is one and the other is Lawrimore. Do a google search for "trailers, Falkville, AL" I have a bumper pull from Lawrimore. Falkville is just north of me...I'm in Cullman. What I have is a dual axle metal deck, capacity about 7.5K, tows great, I've never had an issue with it. I do plan to add two tie down points farther inboard from the rear of the trailer so I can get a better pull down angle on the rear of the truck. I've never had stuff move around but I think its better to have more direct pull strait down to the deck (as best as you can, to secure the truck riding on on the trailer, not that its a direct pull down to the deck, rather it could be, but trying to avoid having the truck rear axle sitting 6 feet from the tie down point which may be at the rear most end of the trailer.
For me, what I have rides good, I don't have to watch the trailer or feel the need to watch it, It tracks well and rides well. None of that shimmy BS or vibration etc and I run an adjustable "normal" hitch not WD. Something marginal becomes a royal pain in the rear on trips or towing because you never know what its going to do or act. I for one hate road repairs so I do what I can to avoid that.
A few things I would want....HD axles as large as you think you would ever need (weight capacity), better tires than the china stuff, marker lights on the fenders so you can tell where you are at night, tie down options on the deck that suit what you will haul or more than just 4...not just stake pockets, but d-rings on the deck or similar, a ramp setup that will not kill you in weight having to deal with it, good HD cable setup for the lights etc and LED lights everywhere, Ability to have two spares mounted on the trailer, Some simple way that works to have a small tool box mounted to hold straps / gear. Of course brakes on both axles. ensure safety chain setup is not a joke.
Drive the empty trailer to see how much noise it makes, and they can make a lot, depending on the ramps. I get tired of hearing that, understanding that somethings are just as they are, but might be worth to understand whats out there and if you want to listen to chains and metal parts rattle around on every bump.
