From the CDL aspect, a class C license is not a CDL license. There is a Class A and a Class B CDL and it is not a trivial thing to get one. A Class C and a pickup truck isn't going to make it.
From the trailer/motorhome aspect, I don't know as I had not problem qualifying, but I am a Travel Supreme 40' and that is definitely an RV Trailer. The question would be how far Dish checks back on the RV registration, like do they contact the state? If they do, the states are very informed on what trailers are RV and what are cargo or utility trailers. Motorhomes are pretty obvious.
