Frequently Asked Questions

Measure the mounting area first, including usable rail or body length, box height and depth, and the space needed for doors, lids, or drawers to open. TopSide boxes range widely in length and configuration, so a box that physically spans the available space can still interfere with mirrors, racks, body hardware, or cargo access. Match the exact dimensions and mounting instructions to the vehicle or trailer before ordering.

Choose the layout around how you need to reach and organize the tools. Door-only boxes maximize open cabinet space; doors with drawers add separated small-item storage; top-lid designs add access from above. OmniGarage also carries slant and straight configurations, so compare the body shape, door swing, drawer access, and cargo area around the box. The best layout is the one you can open and organize without sacrificing needed bed or work-body access.

It depends on the exact box. Some TopSide models include J-hooks, protective rail pads, and other mounting hardware, while other heavy-duty models sell mounting hardware separately. UWS replacement TopSide legs are also sold separately and require two legs, with hardware not included. Check the product’s included-components list and installation sheet before purchase so the box, legs, brackets, and fasteners are all accounted for.
