Camping World RV Sales

I was having trouble wiring my motorhome to my car that I wanted to tow, I called and they said they were the best and have done more than anyone in the city. I made a app't. I went in the next afternoon, and waited in about a hour the service man came in and told me I had no lights on the motorhome at all and said it would have to be checked out and referred me to another shop??? The lights were working when I got there, I asked if he checked the fuse and he said they looked under the hood. (the fuse panel is under the dash) and that was that, He said for them to fix it they would have to rewire everything at a cost over 300 dollars. I left, went out to the motorhome, found the blown fuse in five minutes I was on the way??? What kind of service is that?? they were willing to let me leave without even checking the fuse, and drive away with no lights?? They will never work for me again.
