Thanks for the welcome!
Who wooda thunk something like that would turn to be such a cult favorite? LOL!
Just some more information for seabiscuit:
"Another question: I'm looking to buy an old used truck, now I'm thinking an earlier model than the 4+4 transmissions though they have a real good look to them. I see most have been rebuilt one or two times. Typically how many miles does a rebuilt road truck (say 1980's) go before it needs an engine overhaul, or a transmission overhaul?
And another question: If I have a tractor that is a class 7, with a GVWR of 26,000 - 33,000 lbs, and actually weighs 10,000 lbs, and I pull a trailer that is GVWR of 15,000 lbs would I still need a CDL? I've seen semi trucks with tandem axles that were rated as a Class 6, 7 or 8, what on the truck determines the classification rating?"
Depending on who beat it to death, they last a long time. My truck is all original, never touched and it's a 1959. Figure 500K to 700K before they start to need attention(this all depends on maintenance that has been done).
You can plate the truck for what ever weight you want. Ohio has a 22K plate that would really restrict you and eliminate the need for CDL. If you hang a trailer on the back and you go over 22K you're overweight and will get caught sooner or later. My rig is registered for 33K, and I'm just around 27K with trailer. I was questioned once at scales about this and even though it has historical plates, the weight still comes into play. The heavier the plate, the MORE the cost, as when I had truck plates it cost $340/yr. for 33K lbs.
There is alot of grey area in this as with the change of use that big trucks are getting, the laws have not adjusted to them and even though you can be "legal" per say, someone can "read" the rules a bit different and try to get you in trouble.
I got my CDL to CYA even though in Ohio you don't need it for historical plated vehicles. Since I travel to other states, I don't want issues that will make your day very longggg.
