Fifth Wheel St. (FWS) - Providing important safety information for all RV owners.

We are the one-stop, self-help RV safety website providing tow capacity information, tow ratings, towing guides, and important RV assistance to match up tow vehicles and trailers correctly, the first time. Our weight safety calculators with the industry-leading 13-point Weight Safety Report for 5th wheel or gooseneck trailers and conventional trailers will expose the truth about important load conditions. We provide web based and mobile app calculators and printable worksheets for all RV travelers that assist truck camper owners, all who tow fifth wheel or gooseneck trailers, and conventional trailers such as bumper pull travel trailers, boat trailers, and utility trailers, as well as motorcoaches towing a car or trailer.

Four Easy Steps...

Step 1: Choose, print and provide answers on the appropriate worksheet.

Step 2: Weigh your vehicle with your trailer or other towable attached.

Step 3: Weigh your vehicle without your trailer or other towable attached.

Step 4: Enter the data from your worksheet into the RV Safety Report Calculator.

To Obtain Your Safety Report

Step 5: Adjust load distribution and inflate tires per tire load inflation recommendations.

Are you towing below the load ratings?

The RV Safety & Education Foundation data indicates that 57% of all RVs on the road exceed one or more weight safety ratings.

Additionally, the following exceed at least one rating:

  • 60% of all tow vehicles
  • 51% of all travel trailers
  • 55% of all 5th wheel trailers
  • 50% of all trailers exceed the GVWR

Ensure you're not the one exceeding a load rating.

Did you know...

That on any RV forum you'll read statements similar to the following?

"You cannot change the manufactures tow rating or carrying capacity."


"You may be able to change the capabilities of the truck, if you address all weak links in the chain, but you cannot change the manufacturer's rating."

The big question is, is there any part of this assertion true?

After an informative conversation with a representative at NHTSA, we have an answer. Read the following article to learn more.

34 RV Fire Facts That Can Save Your Life

"Can a F150 or 1500 ( half-ton) truck tow a fifth wheel trailer?"

As evident in the picture above, we at FWS have determined that for typical RV use, many half-ton trucks do not meet the load requirements for the weight of these trailers. The GVWR and/or the GAWR will most likely be overloaded, and some driving conditions may be unsafe, even with the lightest fifth wheel RVs touted for half ton trucks.

Obviously, there are several half-ton trucks towing fifth wheel trailers on the highway. One's ability to tow a fifth wheel is never the issue. The question that must be answered, is, "Are they towing a fifth wheel and not exceeding the truck's ratings printed on the certification label?" (i.e. GVWR and GAWRs)

Always verify truck tow capacity with RV Tow Check.
