Bird,
I guessed what you guessed to /w3tcompact/icons/wink.gif I had a 11.5' 1973 super heavy compared to what is made now camper(wow!). I hauled it up through the Western States and Canada summer before last. I HATE to be under trucked, but I definitely was with that big old camper on my F250. I sure do see a lot of them on 3/4 tons though.
I sold that camper, and got a newer 9.5'. It's lighter in general. It is also made lighter, just by newer material types. It hauls so much nicer. Part of it is there is less "pivoting way out off the back of the truck.
I'm hoping for something mid next year, cross my fingers /w3tcompact/icons/smile.gif My long range goal is a F250 or 2500 series Dodge Turbo Diesel, to haul the camper and two horse trailer. That's still a bit for a 3/4-ton, but doable I believe.
I'm estimating 2000 lbs for Miley two horse trailer, two 1200lb horses. The camper rates out at about 2500 loaded. That's a approximate 6900lbs. i thinks it's plausible, but kinda pushing the outer edge...
