While it is true that only you can determine the suitability of your van for pulling your rig. As indicated you will probably want to upgrade your tow vehicle.
As also mentioned the shell type TTs are an option but a bit more costly.
Here are the figures for our 8600 mile 58 day trip around AZ.
Total miles driven 8500, miles towing 5500. Average camp fee $27.00, average cost per day $89.00.
Our camping fees ranged from $45.00 plus, at full hook up parks to $10.00 for zero hookups in city parks etc. Out west we learned to keep our gas tank full and we carry and extra 5 gallons.
Our daily cost was for every thing, camping, groceries, gas, tourist attractions, souvenir, etc.
This was for two people and a large dog. When we retired we bought bought a 25ft. TT to tour the country. That was five years and 40,000 towing miles ago.
We come from a tent and wilderness canoeing background, so there is nothing in the RVing world that is much more than an inconvenience.
We found that after about 5 weeks on the road, it is about time to head for home.
Finally, you need to know how to change your TT and TV tires. You cannot depend on cell service to call Road Service in some part on the country.
Good luck.
