Frequently Asked Questions About GMC General Truck Sleeper & Related

What years and models of GMC General trucks do these sleeper parts fit?

Our GMC General sleeper parts are designed to fit GMC General trucks manufactured from 1977 to 1987. These parts are specifically engineered for the GMC General series, which includes models like the Brigadier and Astro 95. Always verify your truck's VIN and model year before ordering, as slight variations may exist between early and late production years. If you're unsure about compatibility, our customer service team can help verify fitment with your specific truck details.

Are these sleeper panels made from fiberglass or metal, and how durable are they?

Most GMC General sleeper panels and extensions we carry are manufactured from high-grade fiberglass, which offers excellent durability and weather resistance while being lighter than steel alternatives. The fiberglass construction typically features a gel-coat finish that resists fading and cracking. Some structural components may include steel reinforcements. These materials are designed to withstand road vibration, temperature extremes, and regular wear for many years with proper maintenance.

What tools and skills are needed to install sleeper panels or extensions?

Installing GMC General sleeper components typically requires intermediate mechanical skills and standard shop tools including drill, rivet gun, measuring tape, and basic hand tools. Most installations take 4-8 hours depending on the specific part. You'll need to drill mounting holes, apply sealant, and ensure proper alignment. While many owner-operators successfully complete these installations, some prefer professional installation to ensure proper sealing and structural integrity. Detailed installation instructions are included with most products.

Do you offer both OEM-style and aftermarket options for GMC General sleepers?

Yes, we stock both OEM-specification replacement parts and aftermarket upgrades for GMC General sleepers. OEM-style parts match original factory dimensions and mounting points for direct replacement. Aftermarket options may offer improvements like additional storage compartments, upgraded insulation, or modern amenities. All products clearly indicate whether they're OEM-replacement or aftermarket enhanced. Both types are built to meet or exceed original quality standards.

How do I match the paint or finish on replacement sleeper panels?

Replacement sleeper panels typically come in primer or gel-coat finish, ready for painting to match your truck. For exact color matching, we recommend taking your paint code to a professional automotive paint supplier who can mix the correct shade. Many customers choose to repaint the entire sleeper area during installation for uniform appearance. Some panels feature a neutral white gel-coat that can be left unpainted for a clean, maintenance-free finish. Professional body shops can ensure seamless color matching if needed.
