when i mentioned our Chevy Express van in another thread, some folks asked our setup. Here Goes.
First off, we tow the van with the engine running, in neutral. idling takes about 7 gal of fuel for an 8 hour day behind the bus. a little short of 1/4 tank i think.
We have a Blue Ox 10,000 lb tow bar and baseplate because we have a lot of stuff in the van, so it probably weighs 6000lbs. We use an SMI Air Force One tow brake brake because it is air powered and they could modify it for the power brakes in the van being active. a normal tow brake system would have squealed the tires flat probably becuase they couldn't account for the active power brakes. i don't have, but should have, an idiot light that shows the engine oil pressure in the van as ok. that will get hooked up as soon as i get time or make time. i do leave the camera on and watch for smoke
we tried pulling with the drive shaft disconnected and ran into a couple situations where it was necessary but very inconvenient to reconnect the drive shaft so we could move the van. A drive shaft disconnect device is usually around $1200. even at $3/gal, that's a lot of miles we can go before we use $1200.
We're on our 3rd year at least, towing the van around, probably 30k miles. no detrimental effects short of miles racked up on the odometer.
We drive close to the speed limit, and i usually take the interstates rather than the stop signs and traffic of local roads.
i don't claim my way is perfect. it has just worked out. i have a friend who showed up today pulling his plymouth or dodge van running because his lube pump hasn't shown up yet, but he doesn't want to pull his running all the time. doesn't feel safe.
