User reviews

Good app, lots of potential…

Solid base. If it showed the calculated amounts, differences, it would help in purchasing new equipment. I’d like to be able to enter my truck info and see my max safe travel trailer amounts.

Response from developer

Thank you for your interesting feedback. I'm not sure what you are explaining. Anyone who enters the app's four required weight information should only be from the tow vehicle's specifications. Once the correct info is entered, app users will see max towing weight results for fifth wheel and conventional trailer towing. The results is based on the user's selected pin or tongue weight percentage. All this is thoroughly explained in the app.

Truly useless

This “app” could be done with a simple spread sheet. Don’t waste your time or money trying to figure it out.

Response from developer

Developing a spreadsheet was the beginning of the app creation. However, to date, I have not seen anyone else publish a spreadsheet as accurate as the RV Tow Check app. Apparently, GM recognized the RV Tow Check app value by creating a Trailering Information label that is tailored to work perfectly with the app. For you to assume that everyone knows all the required formulas to calculate realistic vehicle towing capacity is absurd. If you would like to discuss your pretentious response more, please email me at info@RVtowCheck.com.

Waste of $1.99

Does what it says it does, but so does a simple calculator.

Save you money. I lost mine.

Yes - I read the directions and watched to video.

Should be an area to enter your RV specifics.

Response from developer

Sorry to hear about your dissatisfaction with the RV Tow Check app. I would like to help better understand what the app is for and how to correctly use it. I am glad you recognize the app “Does what it says it does.” However, would it not be a bit presumptuous to believe that everyone else knows all four of the calculation methodologies required to achieve a realistic vehicle towing capacity while considering the various pin or tongue weight possibilities? I am glad you know the calculations. If anything, the RV Tow Check app proved your work--is that really a lost investment? There is no need to enter any details about RV specifics when only considering the tow vehicle’s realistic vehicle towing capacity. The important thing is knowing the tow vehicle’s capabilities with various pin or tongue weight percentages selected by the user. Entering RV info does not matter here. I will gladly answer any questions when you email me at info@RVtowCheck.com.

Waste of $1.99

The app was referenced in an article about weighing at a CAT scale. The app doesn’t use hardly any of the numbers achieved during initial and recent-weighs.

It really didn’t tell me anything I didn’t already know from my TV owners manual about maximum trailer weights.

Response from developer

Sorry to hear about your dissatisfaction with the RV Tow Check app. I would like to help better understand what the app is for and how to correctly use it. It is your responsibility to enter a minimum of four required weights: CGWR, GVWR, GVW and the TWR for at least the trailer classification you are considering. The app is not product of CAT Scales nor associated with the RV Tow Check. RV Tow Check's function is only to provide you a realistic vehicle towing capacity of your vehicle. If you were seeking realistic vehicle towing capacity for towing a conventional trailer, it is not uncommon the app results will be the same as the published TWR. However, in cases when the tow vehicles weigh much more than the published curb weight, a realistic TWR will be much less. I will gladly answer any questions when you email me at info@RVtowCheck.com.

If you understand vehicle weights...it works great!

If you understand vehicle weights this can save you some time. Tongue weight as a percentage of total weight needs to fall in the correct range. To me the cautions at the low tongue weight are easily misunderstood.
The red doesn’t mean they aren’t safe...it means your trailer may or may not be able to achieve a low tongue weight. Some can some can’t. The yellow means it is more likely you can reach that tongue percent but again, not all trailers can. The green just means it should be possible for any proper trailer to reach that tongue weight percent.
Maybe overly simplified but a pretty good warning to people too.
Thanks for the app.
