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.

We have created a new segment entitled True Story in our menu above. In our first story, read about Scott's and Heather's frightening RV accident when they overturned their 2006 Tahoe and their 2014 Forest River Classic Super Lite travel trailer. They hope others will learn from their hard lesson.

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.

Heavy Duty Trucks (HDT) for Towing RVs

In recent years, the big three truck makers have really made waves with the extremely high payload and towing capacities. Additionally, the cost of buying these big one ton trucks have skyrocketed as well. For most RVers, the cost of medium duty trucks (MDT), even used ones, are hardly affordable. As you will read in the recommended article, a used and well maintained HDT can be the lowest cost to buy, and it's certainly the safest to tow any RV trailer available. Considering an HDT is a viable option. Read more here.
