What law (specifically, with a link) would someone towing a personal RV be breaking if they were overweight, that DOT could ticket you for?
True , if it is a personal truck and rv, they are not subject to DOT.
Doesn't specifically have to be DOT to wright you an overweight ticket. Here in Texas, Sherrifs and state highway have there own portable scales. Just like it doesn't have to be a DOT officer to wright you a log book violation.
In short , just being overweight is against the law , if it weren't then why do we have a weight limit on our registration. What more proof do you need. Why do you think they have scales at all the inspection stations on the highways. Granted pulling an RV you dont have to go through them , unless you are not running (not for hire).
An RV just exempts you from needing a class A cdl to tow a vehicle that has a gvwr of over 10,001 lbs. Just because you are towing something registered as an RV does not exempt you from the tow vehicles gvcwr rating, or rear axle weight rating.
So technically you can get an over weight ticket if your tow vehicle is not rated to tow what the gvwr is on any trailer, rv or not.
So if you take a half ton pickup let's keep it simple and say it is allowed pull (by the numbers) 11000lbs and have a payload of 1000lbs. Now I know those numbers aren't correct but like I said let's keep it easy.
So let's say this guy buys a camper (rv) and it has a dry weight of 9000lbs. So then he gets it ready with all his stuff and now it weighs 11500lbs. But has a gvwr of 12000. So the trailer is not over weight itself.
He hooks it up to his truck and it now has 1200 tounge weight because he doesn't know how to load a trailer. So now he is over weight on his truck and most likely his rear axle and possibly his tire. And he is also overweight on his gvcwr because his trailer weighs more then 11,000.
So the tickets will be for
over gvwr vehicle A.
Over gvcwr vehicle A
overweight rear axle vehicle A
Possible ticket for underrated tires.
Been driving big trucks along time. I have seen tickets for stuff you not believe, but they were legal tickets.
