If you can afford it, go with the enclosed. I just sold my open 4 and bought an enclosed. I will never go back. I have shelves, heater, and happy family. Does pull harder, no doubt, but only up hill, ride home is no problem.......We park and ride to the cabin for weekend trips. If it snows, no shoveling off the trailer or digging in the back of the truck to find covers etc. Gas and oil will not get stolen and the cab of the truck is free of clutter cause you just put everything in the trailer and leave it. Coat and bib hooks, helmet racks, shoe racks....its great. When we get home I just fire up the heater for a couple of hours and everything inside dries out, no need to haul it into the house. If you look you can find nice older trailers that are very affordable.
