[C&P RV]

Here's some info from Escapee's Guide to Texas Driver's License:

"The table below can help you determine whether you need more than a Class C license in Texas to legally operate your rig. Find the Gross Vehicle Weight Rating (GVWR) of your motorhome or tow vehicle in the first column, the GVWR of your trailer or toad in the second column and the combined GVWR of both vehicles in the third column. The last column shows the class of license you will need.

Be aware that all the regulations use GVWR, which is the maximum weight for which the vehicle is rated. Your vehicle’s actual weight (gross vehicle weight or GVW) does not matter. "

Like BB_TX, I've been towing for nearly 20 years on Class C License based on the same interpretation (Prowler, Everest, Montana 3850FL and now a 3791RD)
