But I have no books right now. They are up in the motorhome where I bought it from. It's a 36 foot Damon Challenger with 8.1 workhorse. It's a 2004. I contacted the lady where it's at, 3 hours away and asked her to find out what class it is. She couldn't find it on the inside placards or doesn't know where to look in the books. Ideas anyone?
