I don't have a clue. I need to move 2 different camper trailers, each about 90 miles. I will be using a 1/2 ton truck to pull them. How much (approximately) do you think these would weigh? Trailer 1: About 26' long, bumper mount, dual axle. It is about 30+ years old. Trailer 2: 1994 model, about 36' long, bumper mount, dual axle (I think). How much tounge weight do campers typically have? Any guesses?
