How to Determine Fit of Lippert Underchassis Double Bin Storage Unit

Question:

I once found a response on your site that said to check the spring center SC measurement on my axel to determine length. I cannot find that response again so…. My campers SC is 74.25. Will one of the Lippert Underchassis Double Bin Storage Units work for my rig?

While I can tell you how to determine fit, the spring centers of your axle won't come into play. In order to determine fit you will just need to make sure the distance between the brackets will line up. There are three brackets going length-wise, and the storage bins have different center-to-center measurements of those brackets:

- 34-1/4" Between Brackets: Lippert Underchassis Double Bin Storage Unit for RVs - 96" Long # LC175180

- 35-1/4" Between Brackets: Lippert Underchassis Double Bin Storage Unit for RVs - 99-1/2" Long # LC236558

The bracket mounting holes are also spaced 22-1/2" wide on these units, and I have added diagrams below of each for a better visual representation of the dimensions.
