>>350503Put a wireless backup camera on the back end of the trailer. Since it's 8ft wide, it's kind of a bitch to see around, even with tow mirrors. It's one of the $70-ish kits from the local auto parts store, they usually have a display by the registers. Took some customizing, but it's been well worth the time. Really handy to have.
Using the camera, I can see the rear corners of the trailer and about 20 feet behind it. Makes navigating the trailer around tight parking lots and not bashing into dumpsters, snow drifts, other cars/trucks, etc a lot easier, not to mention positioning it where you want the loading door to drop down to.
