RV Tow Check 2.1 = RVTC

Revealing the whole truth about
Realistic Vehicle Towing Capacity
in the real world.

RV Tow Check is the only trailer towing calculator app of its kind that supports all manufacturers' weight safety and warranty warnings. RV Tow Check may confirm to what a salesperson told you or reveal an error in information. RV Tow Check displays realistic vehicle towing capacity for fifth wheel and conventional trailers (travel trailers) simultaneously and provides instant results when selecting various kingpin or tongue weight percentages. This is the only towing calculator app RV owners need to use that answers the most often asked question, "How much can my truck or SUV tow?"

RV Tow Check complies with the GCWR and GVWR SAE J2807 TWR Calculation guidelines.

What Others Are Saying

"I just had a tough time deciding which Ram 3500 CC 4x4 to choose. 68RFE or Aisin transmission. Short bed or long bed. SRW or DRW. I choose the long bed, DRW with Aisin. Using the calculator I am golden for towing my 15,500 GVWR 5th wheel. But, if I had chosen the 68RFE transmission, I would be right on the edge. The other options would have put me under." [sic] Heartland RV Club member

"This calculator makes it much more obvious and easy to understand just what we are doing. Thanks." Heartland RV Club member

"I've decided after… punching my daughter's trucks numbers into the RV Tow Check app, there is "NO 1/2 ton 5th wheel" under the 6000 lbs GVWR, that her F150 should be able to safely tow!!! Dad is going to wise up and recommend she shop for a bumper pull." [sic] Heartland RV Club member

Trailer Towing Guides Don't Work As Intended

Practically all towing guides give RVers just enough information that may cause them to purchase a trailer too heavy for their tow vehicle's capabilities. Towing guides listing Maximum Tow Capacity or Tow Limits fail to take into consideration the different towing requirements between 5th wheel and conventional trailers. These common guides do not consider the additional payload weight created by the fifth wheel trailer kingpin weight. Then there is the problem of knowing the real tow capacity of a newly purchased tow vehicle after it is fully loaded with passengers, cargo and a new hitch. Even the creators of the most well known towing guide published by Trailer Life devotes four pages of instructions, entitled "Choose Wisely," that spells out the details required for selecting the correct towing combination.

A Quote From the 2015 Trailer Life Towing Guide

"WEIGHT: The tow-ratings guide in this section lists the maximum tow ratings for vehicles with specific equipment, but many buyers interpret the maximum vehicles' tow ratings with far too much optimism. Always check the manufacturer's figures before making a purchase. The following is an explanation of the terms you need to know which, when combined with readings from a public scale and from your own calculator, should help you determine the correct tow rating for the tow vehicle you plan to buy."

Manufacturer's specs+tow vehicle weight+RV Tow Check=Realistic Vehicle Towing Capacity

Let's get real—None of the towing guides have improved this statistic.

The RV Safety and Education Foundation (RVSEF) data indicates that 60% of all tow vehicles on the road exceed one or more weight safety ratings. "Many of these trucks exceed all of their ratings." (Walter Cannon, RVSEF Video, @14 minutes, 50 seconds)

Even Trailer Life's Towing Guide does not include the weight safety formula for calculating towing capacity based on available payload.

About RV Tow Check 2.1

RV Tow Check is the industry-leading mobile device towing calculator app that safely answers age old questions like these:

  • "How much can I tow?"
  • "How much can my truck tow?"
  • "How much can my SUV tow?"
  • "What is my truck's 5th wheel towing capacity?"
  • "What is my SUV's towing capacity?"
  • "What is my truck's towing capacity?"

The minimum requirement for RV Tow Check requires three inputs by the buyer or dealer. They are: gross combination weight rating (GCWR), gross vehicle weight rating (GVWR) and the gross vehicle weight (GVW). The user has the option to select a fifth wheel hitch if it's not already installed in the truck. They may include any additional unscaled weight for cargo and additional passenger weight. The app does not assume everyone weighs 150 pounds, like the manufacturers do. We believe in keeping our towing capacity calculator simply easy to use, and provide realistic towing capacity that is as accurate as the weights you enter into it.

The RV Tow Check app may look simple on the outside, but the engine on the inside is strong, and the sophisticated math formulas performs multiple calculations and makes decisions that should make any buyer or dealer grateful. RV Tow Check is a GVWR calculator and a GCWR calculator all-in-one. With the three minimally required user inputs and the selection of the highest range of pin and tongue percentages, buyers and dealers can be confident that the RV purchase or sale is unlikely to exceed the vehicle's GCWR, GVWR and GAWR. There are two outputs shown, one for the fifth wheel towing combination and the other for the travel trailer (conventional) towing combination. RV Tow Check is the first app that displays fifth wheel and conventional RV classifications simultaneously, and provides instant results when selecting various pin or tongue percentages.

We're confident that the RV Tow Check app will aid thousands of RV buyers and dealers in making better choices for the RV purchase or sale. Buying an RV is big life investment decision. RV Tow Check will help with part of that decision. Additionally, we anticipate that the RV Tow Check app will become an industry standard for consumers and dealers.
