I saw a lot of RV'er have one a Tail-Mate(http://www.tailmate.com):

But I can't justify the cost of $350! It's some steel tubing, caster wheels, pulley and a $30 winch off of a boat trailer! Raw materials can't cost more than $100 or $150. I think the markup they have on this is RIDICULOUS.
If no one has any great ideas, instead of blowing $350 on a tail-mate, I am going to use the money instead to buy a MIG welder and make one myself. I figure my total cost will be around $300-$350, and I get a free welder out of it!
