As for weight, I come up with this...
Trailer Empty = 6,000lbs
Added LQ Weight = 1,500lbs
Buggy = 4,700
RZR = 1,500lbs
Stuff = 1,500lbs
Total = 15,200lbs
I think that's pretty close. From my reearch, it looks like a lot of toy haulers come in around 16k loaded up.
I can't praise them enough... It's nice to finally deal with people that take a lot of pride in their work. Any time that I call or email with questions (including weekends), they get right back to me. They even let me store the trailer there for 4 months before they even touched it.
As for investment, I'm all in around 28Kish. That includes the cost of the trailer. In the end, everything on it is brand new. The cheapest new I found was around 40K. And that certainly wasn't as fancy as this one. Hopefully this thread will open up a new market for them. Not that I think they're hurting for business. They have folks from Alaska, California, and Idaho bringing them trailers... It's crazy!
