Question:

My sister-in-law needs a frame mount 2 receiver for her Forest River Platinum Wildwood FSX 178BHSKX travel trailer. She has a 2-place bike rack and a bike. Here are the last eight numbers of her vin number XXXXX. What do you recommend? Thank you

Hi Dave,

I'd be happy to help. The VIN unfortunately doesn't provide the frame dimensions needed to identify a hitch, but I was able to look up your Forest River Wildwood FSX 178BHSKX and found the rear frame width to be approximately 71 inches.

Based on that frame width, I recommend the Stromberg Carlson Adjustable Accessory Hitch Receiver # SC45MR. It fits frame widths from 49-1/2 inches to 76-1/2 inches, which puts your trailer well within its adjustment range. I like this option because it was designed specifically for adding accessories such as bike racks and cargo carriers to RVs, and the 2 inch receiver opening makes it compatible with many RV-approved bike racks.

I completely understand wanting to make sure you're getting the right setup before mounting bikes on the back of the trailer. The biggest thing I would still want to verify is that the bike rack itself is rated for use behind a travel trailer. The rear of a trailer experiences significantly more movement and vibration than the back of a vehicle, so it's important that the rack is designed for that environment.

What brand and model bike rack does your sister-in-law have? What type of bikes? How heavy are the bikes?

My sister-in-law purchased a Cravot MagRack F2 Light Weight Foldable Hitch Bike Rack, I contacted Cravot and they told me that they have tested this rack on RVs, SUVs, and passenger cars. What they are worried about is that the hitch system will support the carrier which weighs 42 pounds, and the combined weight of her e-bike and a regular bike. Her e-bike is 46.3 pounds, the other bike will be normal bike. I did a quick measurement of her camper frame, 65' wide inside to inside of frame, height is 5 5/8", it is a I beam frame and the lip measures 1". So, will your recommended hitch still be the right choice after I supplied more information? Please let me know if you need more information. Thank you

@DaveK Thanks for doing that research! Based on the frame dimensions you supplied, the Stromberg Carlson Adjustable Accessory Hitch Receiver # SC45MR would still be my recommendation. Your sister-in-law's I-beam frame exceeds the minimum frame height requirement, and the frame width falls well within the hitch's adjustable range. As for the weight, I don't see any concerns there. The Cravot rack weighs about 42 pounds, the e-bike is 46.3 pounds, and even with a typical adult bike added, the combined weight should remain below the 200-pound tongue weight capacity of the # SC45MR when installed as a bolt-on receiver. If you get it welded by a professional the tongue weight goes up to 300 lbs instead of using the bolt on method. With the measurements you've provided, I still feel confident recommending the # SC45MR for her setup.

Hi Heather and Dave, I purchased and installed one of these Stromberg Carlson adjustable accessory hitch receivers almost three years and 15,000 miles ago on a 20', single axle, Airstream trailer. I use it to carry two regular bikes (not electric) on a two-bike QuikrStuff rack. The Stromberg hitch receiver is very well made and heavy duty. The cross bar is made adjustable by having two sizes of steel square tubing that slide inside each other from each end. There are two bolts in the cross-bar that prevent the center piece from sliding back and forth on the two end pieces. There is enough play between the walls of the inside and outside square tubes that the outer tube of the cross-bar, and thus the receiver, can rotate slightly up and down even with the cross-bar bolts in place. That play can result in several inches of up-and-down motion at the back end of the bike rack. I have a nice dent in the back of the trailer due to an errant handlebar on a rough road. This problem could be fixed by welding the inner and outer tubes to each other. As an alternative, you might be able to tap one wall of the inside tube, drill a hole in the outer tube and bolt the wall of the outer tube tight against the wall of the inside tube (however, the wall thickness may not be enough for the bolt to hold). Another solution might be to use the nut and spring from an anti-rattle hitch-pin on the inside of the inside tube instead of taping the wall of the inside tube. I haven't fixed that problem yet, but I am leaning toward the anti-rattle nut. As Heather points out, there is a lot of motion at the back of a trailer. The result is a large amount of force on the receiver, the rack, and the bikes themselves, so it is important to minimize any play in the system and to be sure all of the components are up to the task. The Stromberg hitch receiver seems quite adequate for this. Finally, I should point out that the weight of the receiver, rack, and bikes all add up. The aft end of a trailer is a bad place to add weight and can induce some extra sway. Emptying tanks and moving weight around in the trailer can reduce the impact of all that extra weight at the back end of the trailer. Hope this sheds some light on the strengths and weaknesses of this hitch receiver.

@BillH Thank you for sharing your experience and all of the detail. Real-world feedback after 15,000 miles is incredibly helpful. You make a great point about the amount of movement that can occur at the rear of a travel trailer. Even a very solid receiver and bike rack setup can experience significant forces and motion on rough roads, which is why adequate clearance between the bikes and trailer is so important. Your experience is also a good reminder to regularly check all mounting points and hardware to minimize any play throughout the system. I appreciate you taking the time to share both the strengths of the Stromberg Carlson receiver and the lessons you've learned along the way. I'm sure this information will be helpful for others considering a rear-mounted bike rack on their RV. It sounds like your QuikrStuff rack has held up well overall, too. Out of curiosity, which QuikrStuff model are you using? It's always helpful to hear long-term feedback from someone who's put that many miles on a rack

@BillH Thanks for the information, it will be a great help. I will pass this on to my sister-in-law, I will recommend that she has it welded for better strength.

@HeatherA It is a Quick Rack Mach 2 with an add-on for a second bike - extremely well made.
