I've taken it 3,000 miles, 2,200 miles, and 1,500 miles. My brother took it 5,900 miles to Sturgis behind a HD Street Glide. Neither one of us had any problems or complaints.
To be honest, I have to check my mirrors every now and then just to make sure it's still with me. I can't even feel it back there. I cut the Harbor Freight frame down to narrow it. It is 6" wider than the Thule carbox, other than that, it is all stock stuff like the article Buck showed.
I was actually referring to the following tips that I have not read in other posts regarding building a home made from HF and Sears:
1-While you're working in the wheel area (preferably before you assemble the spring shackle) cut a piece of 1/2" ID auto heater hose (or garden hose) to fit inside the rear shackle and press the 1/2" bolt through the hose. This will cut down on some of the rattle made by the trailer as it goes over bumps
2- piano hinges to open the lid sideways
3- Tongue Stand Is a WalMart Bicycle Side Stand $4 Bolts Through Existing Hole
4- Swapmeet Cargo Net Attached To Lid With "S" Hooks & Eyebolts. As Lid Closes, Net Stretches Over Cargo Holding Everything In Place
5- Floorboards Make A Great Cooler Rack.This Rack Is Made From a Cast Off Set of Indian MC Floorboards (any brand will do) and a couple of pieces of 1/2" square aluminum tubing. The tubing is notched in the center with an aluminum spacer in the slotted section to keep the bolts from crushing the tubing and add stability. A solid bar of aluminum or steel would work as well.
6- Truck Box Liner keeps things in toolboxes from rattling so it works great in the floor of the carrier
