We have some unique experience that may help you. We have owned two towable RVs, then a class C and finally a Class A. The towable units are less expensive if you already have a tow vehicle. Keep in mind that they require extra equipment that motorhomes typically include such as a generator leveling, boards, tow hitch (we had a $3000 Hensley hitch for safety). I also added a 100 gallon fuel tank to my 1 ton gasoline truck due to range issues in remote areas. All of this can make the cost similar to a class C new. Truck $60,000 + hitch and miscellaneous $5000, Travel trailer suitable for 4 season use $50,000. A class c is based on a van cutaway chassis the most capable and affordable is the E450. The thing to consider is they tend to be very loud when running. The wheel cut combined with the wheelbase means they have a large turning radius. Our 31’ Class C had a 218” wheelbase and a 45 degree wheel cut. Our 34’ Class A DP has a 208” wheelbase and a 55 degree wheelcut. I was mistaken that any Ford dealer could work on it. Trust me they won’t. Only Ford certified commercial truck shops will work on them. Keep in mind if you chose a motorhome of any kind and wish to tow a toad you will need a tow bar and brake system these typically cost between $3500 - $5000 installed. We love our DP Class A. It is quiet and easy to drive, the generator is very quiet as well. The systems are well integrated such as automatic generator start, whole house inverter system, residential refrigerator.
