I have towed my enclosed 20' car trailer and have not had a problem at any of the R V parks I have stayed at. I do recommend getting a RV Campground Book so you can review the CG you might be interested in staying. An open car trailer either 18 or 20' would surfice based on the length of your van. Another consideration is the towing capacity of the MH you buy. MOST 40' DP's have 10K towing rating. Some CG's have pull through sites that are long enough so you do not need to disconnect the trailer. Being new to driving a MH and towing a trailer you will need to become educated with using a car trailer,loadin and securing the vehicle and general driving the combined unit if you have no previous experience with either.
