dont do a air compressor mount a nitogen tank in the trailer then you dont have to wait for a compressor to build up and it is quite! also i dont know how much weight your car is but i have a superwinch 5000lbs winch in mine, you dont want to small of a winch and the money difference isnt that much. The best generator on the market for a trailer is a onan, they are super quite! cabnets are also nice. 110 lights are awsome too. if you want to pm me I can send you a pic of the inside of my trailer so you can see how its laid out. If you use your trailer alot the best thing to buy is a electric jack in the front, hand cranking them is a pain in the butt after awhile.
