Can be $300 to $4000 !!
I go on about 2-3 trips during the riding season with a trailer. I went on the cheap, with the Harbor Freight one for $270 on sale. Put it together, repacked the wheel bearings (as they use some cheap clear vasoline stuff) with good grease. Also put down a rubber seal from the hardware store on the lid to seal it up better, as it is just fiberglass laying on fiberglass.
Got over 1000 miles on it, no problems. Can't even tell it's there, the 1330 has so much torque! The hardest part was doing the wiring. Got the kit from show chrome, plugged into the factory harness with ease, but it was 5 wire, no the 4 wire type of my trailer. Went to Autozone and got a $25 adapter kit, wired it in and mounted next to the showchrome harness, and all was well. By the way, the Showchrome harness uses relays. The signal from Nanny just turns on the relay to activate the lights. There is a power wire run to the battery & ground that is separate. So if anything shorts, no excess power will be drawn from the computer, harming it. I posted a few pics on the RT forum. The only thing I found was my hitch assembly is very tight, I have to yank on the bar to get it off the ball; and the hooks on the chains fall out of the holes from bouncing on the road. I keep a roll of black tape to tape the hook so it can't bounce out.
I went with the showchrome trailer hitch as well. Mounted easy. Didn't spring for the mud flap, thinking it was just a farkle. It is NOT:yikes: ! The back of my RT as well as the back of my wife's helmet got covered with mud and junk riding in the rain! Ordered the mud flap! All in all was about $550 or so I think. The only thing I don't care for is the tongue seems short. Would have liked to see another foot longer. Can't extend it as the trailer has some weird rectangular dimensions, and nothing from harbor Freight will fit it.
Maybe when I retire and am traveling a lot I'll get the BRP trailer, it does look nice! Plus Pete over at WrapMySpyder.com has awesome kits to dress it up.
Just my thoughts!
