Swanny ,I got a business card from a guy last year that has the metavic emblem on the card. Try www.payeur.com
Tire pressure is real important. I don't know what tire you're running, but I run 10 ply bias tires on one trailer. Max pressure is 75 psi, and if you're hauling max loads you need max pressure. This trailer is rated at 14K and weighs 5200 lbs. and I haul my 12000 lb skidder on it regularly.
The tire's on my dump trailer are 10 ply rated radials. They call for 80 psi. so that's what they get.
It's amazing what that extra 15 to 20 psi. will do for your tires. I check mine every time I hook up.

So how do you all move logs?
