Hi radioisotope
My second 454-30 w/179 inch wheel base, is rated at 8500 lbs. dry curb weight with no bed, just cab, chassis and drive-chain.
I had to remove the outside rear duals to load on a heavy duty car trailer. The weight of the truck and car trailer was just over 10,000 lbs. on the scales. The rear duals are a couple of inches under 96 inches (8 feet) in width. If I remember rightly 92 inches outside to outside.
Your truck should have a 161 wheel base (center of front axle to center of rear axle) and a chassis/cab/drive-train unladen weight of about 8,000 lbs. then add any bed or other equipment.
A heavy duty backhoe trailer with surge brakes should do the trick. You will need at least a one ton truck to pull it.
I made the mistake of using a 3/4 ton pickup, could only drive between 25 to 30 MPH, over that and it would start to fish-tail all over the road. And 5 MPH down-hill
I was luckier with my first 1952 GMC 454, I drove it home. Got a one day moving permit to move it home, from my local DMV.
Be patient and drive slow, enjoy you new toy and what you have to look forward too.
