LOL ... all these answers, and not ONE lives or drives on a regular basis in Texas. They don't understand that the DPS in Texas set on the roads and stops RV's and any other truck they wish for weighing, fuel checks and vehicle inspections. It makes NO difference if you are commercial or an RV, if DPS is holding court on the side of the road, you BETTER be legal, especially with Texas plates. Go down to the DMV and talk to the supervisor about what is and is NOT legal in your case, then ask for a copy of the law(s) he or she is citing, for your protection.
