If you're planning on buying anything from GL, visit
www.steelsoldiers.com first and read-up. You've gotta submit some paperwork and pass a background check before you'll be allowed to purchase a vehicle or trailer like either of these. It can take up to about a month and a half to get your first purchase approved, so that's something else to think about.
I'm going to pick up my trailer next week. This is the first time I've bought anything from GL and it's been a painless experience, but that's not always the case jusding from what I've read online.
