Looks pretty cool! You should mount one on the front for the wifey! I was expecting to see a dog carrier on the back of your bike for Mitsu. Where does he ride?

I noticed in the one close up photo of the droop that it looked like there was a gap between the outer part of the hitch assembly and the frame. Are the bolts under there torqued? I'm wondering if you loosen of the bumper mounting bolts then tighten up the frame bolts, then re-tighten the ones on the bumper the hitch itself would sit more level. Or maybe I'm seeing things?

I've never tied down anything as heavy as your bike but I've tied down plenty of duel suspension mountain bikes. You may want to run tied downs up to the bars and use them to suck down the suspension. This will keep more tension on the tie downs and it should ride a little better without moving around. Otherwise when you hit a big bump the bikes suspension may compress taking tensions off the tie downs.

Well I guess we don't need to haul your bike to the dealer in the Frontier anymore?
