RVTC Interactive Demo

This web-based demo is designed for online use and does not appear precisely like the RVTC app. However, the math calculations are identical.

Walter and Hazel found the fifth wheel RV of their dreams. The dry weight is 12,277 pounds. After Water's excellent advice from members of a Facebook RV group, he will look for a truck that will tow a trailer's GVWR. Walter called the RV salesman and learned the trailer's GVWR is 16,000 pounds. The following day, Walter and Hazel found a truck they really like. The car salesman told them the truck has a towing capacity of 18,500 pounds and will tow the trailer fine.

Should Walter and Hazel believe the car salesman?

To be sure he will not make a costly mistake, Walter purchased the RV Tow Check App to learn the truck's realistic vehicle towing capacity.

Below is the picture Walter took of the trailering information label on the truck. The truck does not have a 5th wheel hitch installed.


For this demo, all the required truck trailering information is entered and may not be changed.

Walter estimated he would have about 150 pounds of cargo.

Walter, Hazel, and their German Shepard weigh 405 pounds.
