Original setup was old 1/2 ton V8 van, lightweight and terribly built open trailer carrying a 1350# car. Trailer had lt truck tires. I probably went thru more tires on the van and trailer than the race car...rarely made trips further than 4 hours without at least one shreaded tire from split belts. Obviously I carried waaay too much in the van(s). Often couldn't hear the blowouts cause the van was so loud, and kept trying to drown out the noise with the radio. I think I sort of specialized in loud, ugly, high mileage towing vans, eventually owning at least 4, but they generally got about 12-13 mpg at 70.
Next, better trailer, could carry more than the car on it. Led to more blown trailer tires than van tires.
Next up, 3/4 ton'84 Suburban with a 4 bbl. Wopping 6mpg. Never blew 'Burb tires out, learned about meaty, beefy, big, and bouncy. Eventually got a '93 Burb, 10-12 mpg. Woohoo!
"Graduated" to Ford dually with 454 and 22' enclosed. Back to 6-7mpg, and the pig wouldn't even go up hills at the speed limit. Learned to hate that truck, but have to admit I never blew a tire in it - and they were Firestone ATX!
Bit the bullet and went the conspicuous consumption route....new Chevy dually with 8.1 gasser. Gas prices have curbed many of my bad habits, learning to tow at 60 mph, and getting about 9.5-10 mpg as a result (about 8.5 when old bad habits return). Nice and quiet, very comfortable, can go up hills at 90 if I want to, and I actually arrive at the track almost relaxed. Well, as relaxed as I can be considering it took me an extra hour to get there.
Maybe I should go back to an open trailer and only race at my local track unless/until the gas prices come down...
