Hey John, so the correct amount of spring bar tension will be based on the trailer's tongue weight and how it affects the suspension of your Nissan Frontier. Every WD system is a little different but what it comes down to typically is…

I got some information from Yakima and included a diagram of the EXO SwingBase #Y34VR, which is the base part for the EXO SwingBase 2 Tier #Y82VR. Though the measurement from the pin hole to the closest edge of the carrier is not included in said…

The UWS tool box part #UWS01039 that you referenced is made from 13 gauge aluminum which is .090 of an inch thick.

The UWS A-Frame Trailer Toolbox #UWS01039 measures 18" wide on the outside so if you use the larger Ego batteries that give you the 18" this won't be wide enough and you'll need to use a different box like the DeeZee…

Choosing the right height setting for your 5th wheel hitch is a combination of a few different variables. First of all you want your towing setup to be as level as possible. With your Montana High Country 340BH level you will want to measure from…

I spoke with Access. The Toolbox Edition Soft, Roll-Up Tonneau Cover, part #A62439, is designed to fit behind toolboxes that between 19" and 21". With yours being only a half-inch longer than that, they stated that it would be a tight fit,…

There are limited solutions for the tool box and rolling hard cover. I recommend the UWS Truck Bed Chest - Secure Lock Under Tonneau Series - 8.85 cu ft - Bright Aluminum #UWS08297 or the UWS Truck Bed Chest - Secure Lock Under Tonneau Series - 8.85…
