i have used several trailers. open landscape trailer hauled with a 1500 V6 Silverado 6x12 enclosed hauled by my titan 3 rail trailer hauled with the Sonata as much as i love having an enclosed trailer, and not have to worry about space. I can throw everything and anything i wanted in it. but unless you are hauling a few buddies with you that will chip in some cash, its not worth it IMO. I was getting 10mpg haulin 2 bikes and gear in the enclosed trailer with my titan. i got 23 mpg hauling my ducati out to colorado, gear, luggage, toolbox and what not in the trunk of the car. so for my its ALOT cheaper to do a small open trailer pulled behind the car than lugging a huge enclosed trailer with more space, if i could get a toy hauler, then it would be better worth it, i would be saving the cost of a place to stay. so my rig this year will be the 4x8 open trailer im putting together. you have seen the pics. single axel, leaf spring suspension, will hold 1700lbs. Ill be able to haul 2 bikes on it, and ill have a place for my canopy for track days, as well as a place underneath for my ramp. Ill either do a small v shape rock guard up front and a place for gas cans behind it, or a lock box type thing instead.
