I can't tell you how much I appreciate your offer. I'm looking at a pile of bolts, plates and angles and have no idea as to what is going on. I'd imagine the larger trailer is basically the same as mine. Just a starting point would be fine. I imagine I can figure it out after I have a starting point.
As far as speed rating, the bike guys typically buy an HF trailer, affix a Sears car top carrier to it and pack their stuff in there to haul all over the planet. There's tons of debate on the bike trailer forum as to which is better, 8 inch or 12 inch, but to date the only real variable seems to be personal preference. I went with the smaller wheels in the hope that I might be able to build out over them a bit.
I'm building mine to sleep in on an emergency basis in Baton Rouge, but primarily envision is as a vehicle for getting my gear to those wild motorcycle rallies I've come to know and love. I want to be able to pull up to the rally with my beer cold, my chair handy, and my cooler full of 400 jello shots ready to consume. When I'm heading to the rallies I'll be loaded up and won't be riding at breakneck speeds. When I'm going to Baton Rouge I'll likely be traveling very light and plan on having little more than a sleeping bag, 30 pounds worth of tools and clothes, and a folding stock mini-14 with a 30 round magazine stored in a recessed floor compartment.
BTW, anyone know the gun laws of Louisiana? In Texas we can carry a loaded shotgun or rifle with no trouble. Is it the same in Cajun country?
