I can take a 4 cylinder automatic Ford Ranger and stuff a Dana 60 front axle and Dana 80 DRW rear axle under it with Rickson 19.5" tire and wheel conversions with no changes to the vehicle's engine, transmission, cooling capabilities, chassis strength, etc. According to the law as you want to quote it, I can now tow heavy 5th wheels with this rig since I'm not exceeding axle and tire capacities.
I've have consistanly stated "the vehicle manufactures FAWR/RAWR/tire capacities".

I'll repost the PA weight reg for you :
(c) Gross weight.--
"No vehicle or combination shall be driven
with a gross weight in excess of the sum of the allowable axle
weights as set forth in this section, nor shall any vehicle or
combination be driven with a gross weight in excess of the sum
of the manufacturer's rated axle capacities.".

If you will notice the wording says the "vehicle" manufactures axle ratings cannot be exceeded. Not your case scenario which exceeds the Ford Rangers certified GAWRs on the drivers side door post. tires on a truck are tied to the truck manufactures GAWRs per the FMVSS's

That you tell everyone that they should stay within certain manufactures numbers is fine. However IMO the truck owner/operator should know that there are legal weight limits for any truck. A tow vehicle owner owes it to himself and others on the road, that he's not towing illegally as the Ford Ranger scenario would be. Weight regs are about vehicle safety once you know what they say and how their enforced.

Thank you very much for that affirmation. That's what I'll continue to do.

I agree with Ken - this horse has been beaten long enough.
