My recently converted M105A2 trailer...converted to 12-volt LEDs, 2-inch-ball hydraulic surge brakes (no air), former Deuce splash shields with custom-cut mudflaps, fully DOT-compliant. Just got the cargo cover re-installed; the nylon ropes attached to the cover were dry-rotted, so I cut them off and used 7/16" rubber rope with metal hooks.
Brakes were fully adjusted, and under a hard, quick stop I can get the trailer tires to lock up (when the trailer is empty), so I know the surge coupler is doing its job perfectly. And my blister gained when bleeding the brake lines wasn't in vain!
I like the M105 series since my quads & side-by-sides fit into them without any drama, as well as any other gear/tools I want to take along. So these M105A2 conversions are the perfect ticket for me. I retained the 24-volt brake lights in case I want to tow this with my Deuce, once I get the receiver hitch installed. It tows very well and I really enjoy it.
