A DMP awning is custom-built to your trailer, so a clean install starts with good measurements. This guide covers what we need from you, how to mark your mount line, and how to hang, tension, and store the awning so it sets up fast and sits tight every weekend. Most of it is straightforward — and if anything isn't, call us and we'll walk you through it.
What you'll need
- A tape measure (25 ft is plenty) and a helper for the longer runs.
- A pencil or marker and masking tape to mark your mount line.
- A level and a step stool or ladder.
- Basic hand tools for the included stainless mounting hardware.
That's it. Because the quick connect/disconnect system and brackets are built to your trailer, you're mounting to a known layout — not improvising.
Measuring your trailer
Before we build anything, we confirm the key dimensions with you. The big ones:
- Mounting length. The usable run along the side of the trailer where the awning will mount — this sets the awning length.
- Mounting height. How high the mount line sits off the ground, so the awning clears your work area and any roll-up doors.
- Side and obstructions. Which side the awning goes on, plus the location of doors, vents, lights, and trim that the brackets need to work around.
- Free-hanging span. Our awnings free-hang 12–14 ft with no legs; we confirm the span that fits your rig and how you run.
Send those numbers (and a couple of photos of the trailer side) with your quote and we'll spec the build. When in doubt, measure twice — a few minutes up front saves a return trip later.
Marking the mount line
With the awning in hand, hold or tape your bracket positions along the planned mount line and use a level to make sure the line is true end-to-end. Mark the bracket holes, double-check height and clearance over your work area, and confirm nothing fouls a door or vent before you drill. A straight, level mount line is the single biggest factor in how clean the awning hangs.
Installing the awning
- Mount the brackets. Fasten the billet brackets to your marked line with the included stainless hardware. Snug, square, and level.
- Set the frame. Connect the heavy aluminum A-frame to the brackets using the quick connect/disconnect system.
- Hang the cover. Run the fabric onto the frame and close the one-piece zipper so the cover seats evenly.
- Tension and check. Take up any slack so the fabric pulls tight and the free-hanging span sits flat, then step back and confirm it's level.
Setup, teardown & storage
Once the brackets are mounted, day-to-day use is quick. The quick connect/disconnect system lets one or two people deploy the awning trackside in minutes and break it down just as fast when you're loading out. Between events, the cover packs into the included fabric storage bag and stows in the trailer — the one-piece zipper means there are no loose parts to lose.
Tips & common mistakes
- Don't rush the mount line. If it's not level, the awning won't hang clean no matter how good the build is.
- Mind your clearance. Confirm the awning clears roll-up doors, ramps, and your work height before drilling.
- Keep hardware stainless. Everything we ship is stainless — if you swap a fastener, match it so nothing seizes after a wet weekend.
- Pack it dry when you can. Stow the cover dry to keep it fresh; if you have to pack it wet, air it out at home.
