Unless you have a camper shell on it...
When was the last time you tried doing that or checked with DMV about it? They will not allow it anymore. You used to be able to register a truck non commercial about 20 years ago if there was a camper or camper shell on it but if you removed the camper or camper shell and carried as much as a bag of groceries you better be able to pay the HUGE fine. This is why DMV no longer allows it. People would use that excuse (camper/camper shell) to get around paying weight fees.


and my **** is a stock 6.6 ltr 01 duramax with a tow tune on it. 420+ RWHP and 900 RWTQ
