1) How do we know the pickup in the original post was a half ton? It only mentioned it was a Chevy Silverado. Silverado's were available in 1500, 2500, and 3500.
We don't with certainty but I believe it was a reasonable assumption to make. Use of ordinary 1/2 ton pickups as part-time pullers of conventional travel trailers is fairly common across the south. If the truck had been adequate for the trailer, ie a 2500 or 3500/dually, would the LA HP issue that caution comment? I don't think so.
The fact that a citation was not issued indicates the truck was probably not overloaded but was inadequate for towing.
What is your point?
My point was it is a bad idea to tow a large travel trailer with a 1/2 ton pickup due to soft springs and soft sidewalls in passenger car tires. Do you disagree with that? Do you think it is acceptable?
2) How do we know the truck was overloaded? No where did it say the truck was LEGALLY overloaded. Just a HP reminding everyone to tow with a vehicle of adequate size.
Same answer. I don't think the truck was overloaded, I think it was inadequate for towing.
3) From what I know, Harvey is right about DOT weight enforcement. He is also right about GCVWR engine and drivetrain design limitations. However, design of the brake system is also based on the GCVWR.
No it is not. It is expected and required by law that all but tiny little 1500 lb. trailers will have separate trailer brakes. The size and requirement varies slightly among states. No one, not the truck manufacturer, the trailer manufacturer, DOT rules, or drivers expect the truck to stop a large trailer w/o brakes. It is illegal to tow a trailer without separate trailer brakes above certain minimum weights (like 1500 lbs. ) in every state. DOT rules specifically address trailer brakes including light trucks used for towing trailers.
This legal limit means that the tow vehicle cannot and is not expected to provide stopping power for the combined weight anymore than an OTR tractor is limited to its GVWR. An OTR truck has two different rated weights just like our dually pickups. An OTR truck has a GVWR which is about 50,000 lbs. (based on tires and axles) but it can tow a gross combined weight of up to 80,000 lbs. , up to more than 100k lbs. when specially permitted. An OTR tractor cannot stop 80k or 100k loads w/o trailer brakes anymore than a dually pickup can stop 24k or 28k lbs. w/o trailer brakes.
But, what about civil liabilities? I personally can't risk financial disaster from exceeding the GCVWR. So how do we protect ourselves from the ambulance chasers?
Why do you assume that if someone has an accident while pulling a trailer that does not exceed any legal weights on the truck or the trailer, is legally registered, and legal to tow with the driver's license possessed by the driver, and legal to tow in the state where the accident occurs, that that driver is subject to civil liability? That assumption is based on the old phony weight police argument of the internet. I know of no example of such laws in existence and no examples of anyone ever losing a lawsuit over such an issue. Do you?
No one can be absolutely certain that he or she will not be sued by some loser wanting something for nothing who finds an ambulance chaser to take his case. It occurs in courtroom all over the country every week. Nobody is safe from ambulance chasers and those who seek to extort money from others via the courts. That is the reason that many of us have been in favor of tort reform for years.
But that is the reason why we have insurance. If I am involved in an acccident my insurance company will defend me. The insurance company would hire a good attorney who would subpoena witnesses such as experienced and credible DOT officers who would testify in court that it is perfectly legal to tow up to the limits of the truck which are posted on the VIN sticker and on the registation. If it were a potentially large lawsuit the attorney would also subpoena manufacturer's engineers to testify about the way weight limits are determined.
