I don't see why no title is a big deal. Various terms apply to salvaged vehicles or home builts. Years ago I bought a small home made utility trailer in Colorado, and with a bill of sale, got a VIN and title in Maryland. With or without a title, Colorado requires a VIN inspection before it will issue a registration for any vehicle brough in from another state.
OTOH, the world is full of campers needing a good home! Keep searching. If you do buy this camper, don't pay more than you are willing to lose, plus disposal fees. Or just take your dough to a rolling craps game. Chances of coming out ahead are about the same.
