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.
