Frequently Asked Questions
What is the main benefit of using the RV2 9-Inch Offset Adapter?
The RV2 allows you to tow your 5th wheel trailer using a standard 2-5/16″ gooseneck ball. This setup is ideal for owners who want to keep their truck bed clear for full use when they aren’t towing, avoiding the need for a bulky, permanent 5th wheel hitch.
How does the 9-inch offset help my towing setup?
The 9-inch offset shifts the trailer rearward, providing critical extra clearance between the trailer nose and the truck cab. This is especially helpful for short-bed trucks, allowing for tighter turns without the risk of cab contact.
What is the weight rating for this adapter?
The RV2 is built for serious hauling, featuring a 24,000 lbs. Gross Trailer Weight (GTW) rating and a 6,000 lbs. Gross Tongue Weight (VTW) rating.
Is the height of the RV2 adjustable?
Yes. The adapter offers 4 inches of vertical adjustment (from 12.5″ to 16.5″) in 1-inch increments. To ensure a level ride, measure from the top of your gooseneck ball to your trailer’s kingpin plate before installation.
Does it fit all 5th wheel trailers?
The RV2 is designed to fit Standard OEM trailer kingpin boxes ONLY. It is not recommended for kingpins over 18″ in length or for pin boxes that feature built-in cushions or movement (air-ride or pivoting pin boxes).
How does the coupling mechanism work?
It features our precision-cast GN8 self-latching coupler. It locks automatically when lowered onto the ball and can be released remotely using the provided cable assembly, so you never have to climb into the truck bed to unlatch.
Is the adapter easy to install?
Yes, it is a straightforward bolt-on installation. However, the top box must be bolted or welded to the pin box in conjunction with the provided clamp block connector. If you are unsure at any stage, please contact our technical team at 620-431-9196 for clarification.
Can I lock the coupler for security?
Yes. The coupler is pre-drilled to accommodate a standard padlock, allowing you to secure your trailer and prevent unauthorized uncoupling.
What kind of finish does the RV2 have?
The adapter is finished with a durable black powder coat to resist corrosion and stand up to harsh road conditions and weather.

What our customers are saying
“This is a 2019 Ford F-150 with 5’5” bed. I was worried about finding a product to get the clearance I needed to pull my horse trailer . My trailer is almost 79 inches wide . Installed the SB116 16” inch extension coupler on my trailer and I’ve pulled it several trips now and it works great. My trailer pulls great due to load is on the truck where it needs to be. Very well made and love the fact I don’t have to get up in the back of truck or reach over the bedside to hook up and unhook. The folks at PopUp Towing were great to deal with and answered all my questions.”
- Mark G.
“We installed a CAG (Connect-Adapt-Go) from PopUp Towing on a truck recently. It went in very easily. Instructions were very clear and we are very pleased in the outcome. We will definitely do more business with PopUp Towing.”
- Rick & Jean Horsch
“We purchased a CC2 Cushion Coupler by PopUp Towing. I’ll tell you what, after arriving home from the last horse show, we were amazed to find two cans of pop that were left on the dinette table still on the table. Now that’s a smooth ride!”
- Larry P.
“I was having trouble explaining my issue and determining a solution to my turning issue when towing my gooseneck trailer. A friend of mine said, you should try to call the guys at PopUp Towing as they helped solve his issues. Let me tell you, I spoke with two gentlemen at PopUp if I remember correctly their names were Derrick and Chance, those to guys seem to have more knowledgeable information than anyone I’ve spoken with in this industry. Years of valuable knowledge, and highly recommended if you have similar issues. Thanks again and I absolutely love the new RVGC complete pinbox replacement to allow me to tow my 5th wheel without the bulky 5th wheel hitch taking up my bed space.”
- Bill F.
