We bought our cart before we ever bought our first camper. We used to either tent camp, or rent a cabin at our resort, but the cabin rental started getting expensive, and more of a hassle than tent camping. We bought our first camper used, and it was not in the greatest shape, but we parked it on a seasonal site, so it didn't matter, since we didn't plan to tow it anywhere. When we bought the new camper, we opted for a toy hauler so we could be mobile, and still take the cart with us. Plus it makes a nice place to keep the cart out of the elements during the winter. The cart is well worth the investment, as far as towing options, I don't know that I can offer much, other than to suggest a toy hauler, but it sounds like that is not an option either, since you already have your camper.
