Haulmark, Featherlite and before they went south, Pace all offer a motorcycle grade trailer that is called a Lo-Hauler or something similiar. I have had several and none of them cost me extra because they were purpose built low enough to go into a standard garage door opening. Currently the Haulmark is probably one of the easiest to deal with, they have a great warranty, they have made it thru the economy situation without going under (like Pace) and they will build in whatever you want from the start, you just need a good dealer to help you. They do charge extra for factory pick-up but normally this will save you still vs freight and you can look it over before it leaves the factory. Factories are located all across the country as well.
Some suggestions. If you order one get the seamless/screwless outer skin and have them run it front to rear vs the normal top to bottom. Stuff is about 48" wide and even a screwless trailer will have a seam every four feet when skin runs vertical and if run front to back - completely smooth. Order the polished or alum treadplate on lower section all the way around the trailer, it looks cool and does not chip from stuff being kicked up like the painted surfaces. Get white vinyl or alum on interior walls and ceiling, you will love it first dark night with only 2 1156 bulbs for lighting when you are trying to load/tie down. Not sure current cost but white vinyl interior was $11/foot in 2010. So ten foot trailer = $111.00 = cheap!
Soon as you get it home, wait until after dark, turn on interior lights of the trailer and close all the doors then get under the trailer and caulk, with black urethane caulk everywhere you can see light coming thru. You will be suprised.
If you want fixtures, paper towel roller, handcleaner wax shelf that won't spill, umbrella holder or whatever go with PitPal brand, Stuff is impossible to beat, will last lifetime. Summitt, Amazon etc or direct from company (Amazon no shipping or tax).
JMHO.
