Hey Clifford, so in your situation what you'll want to do is inflate the bags with the amount of air you want in them first and then set the WD system up after that. So you will end up using less spring bar tension so you'll need to make some…

The Viair Portable RV Air Compressor Kit for 5th Wheels and Travel Trailers part #VA39WR is a bit too small for 35" tires. Instead, you'd need to bump this up to the next size which is the Viair Automatic RV Portable Air Compressor for Class…

Hey Rick, yes the EcoHitch Stealth hitch part #EH57CR that you referenced does fit your 2024 Subaru Crosstrek Wilderness edition. This is a really great option to carry a bike rack. There's no trimming of the bumper required nor does the exhaust…

I recommend the Wheel Masters 4-Hose Inflation Kit #WM8001-135 for the rear of your 2022 Jayco Greyhawk 27U RV motorhome. This will allow you to easily access both the inner and outer tires to add or release air when needed. For the front tires you…

I believe the 2022 Ford F-450 Super Duty has 19.5" wheels, verify this for your vehicle. I suggest the Wheel Masters 4-Hose Inflation Kit, #WM8001 which is for wheels up to 19.5".

Hey Linda, The listed length of your pop-up is showing as 17' so the body is likely more in the 14' to 15' range, but you'll want to measure the body of the trailer like the diagram below to confirm. If the trailer body is 14' to…
