Which overland cap is lightest?
The Westin EXP is extruded aluminum, which Westin says is lighter than fiberglass or steel caps. The Ascend, OVS, and Rough Country caps are steel or stainless steel.
Do these caps require drilling?
OVS and Westin both list no-drill installation. Rough Country's cap fastens to the vehicle body. We install every cap in our bays and check fit, seals, and locks before you leave.
Do these caps fit heavy-duty trucks?
OVS and Westin both offer 2500 and 3500 fitments for Ford, GM, and Ram. The Ascend launched on half-ton and midsize trucks only. Send us your truck and we confirm fitment.
Can I bring a cap I bought online for you to install?
We don't install customer-supplied parts. Our pricing is competitive with online, and buying through us means we own fitment, install, and any warranty claim.
Do you offer financing on truck caps?
Yes. Standard and flexible-approval options are available. See our financing page.
