My current rig (around 28 feet from ball to bumper) is great for the renaissance faire. Even though it has no slides and just one pass through basement storage compartment, it has a nice one ton OCCC. All my armor and such fits well inside, so I can just take it, store it, and come next season, pull it out and have everything ready to go.
However, because it is so big, I can't really use it for much other than that. It won't be for a while, but I do plan to eventually trade it in for a class "B" or a truck camper. Some vehicle I can use on a weekly basis to get out of town with ease.
