The dual rail Kendon trailer has a heavy duty powder coated steel frame, the Dexter Torflex axle, automotive grade sealed wheel bearings with Zerk fittings, high quality chrome spoke wheels mounted with 13-inch ST rated radial tires (Service trailer rating), and a nice tongue mounted utility box. You could load two full-sized bagger Harleys on my Kendon dual rail trailer (with its 2200 lb capacity) and easily haul them across the country if you wanted to. It's designed for that and everything in between. The Northern Tool (and other small utility) trailers won't hold a candle to the kind of service the Kendon is designed for. And for $1,200 bucks used? Pffft. No brainer for me.
Uses for a trailer you ask? I like it for taking the dirt bike and the FJR up to the mountains for a long weekend of street (FJR) and trail (DRZ) riding in the western NC mountains. Cherohala, Deals Gap. Blue Ridge Parkway areas all offer lots of both. Another fantastic recent use for my motorcycle trailer: last September a buddy & I towed our FJRs from Atlanta to Galax, VA so we could spend a week riding western VA and up into the WV mountains. That cut out all the monotonous Interstate riding giving us old farts 10 hours total (5 up and 5 back) of time to bitch and moan about how bad everything is in our miserable f-ing lives lol.
