Coleman TSR Rooftop AC Install Kit | 48203-1201

The Coleman TSR Rooftop AC Installation Kit is the mounting hardware that ties your rooftop air conditioner down to the RV roof. It's the genuine Coleman kit, part number 48203-1201, and it ships with the roof gasket, four self-drilling screws, and washers that carry their own sealing gaskets. Small parts. But they're the ones standing between your cabin and a rain leak.

Here's the thing about a rooftop AC install. The unit itself is the easy part. What actually keeps the water out is the gasket sitting between the base of the AC and the roof opening. That foam gasket compresses as you snug the unit down, and it seals the whole perimeter. When that gasket is flattened, cracked, or missing after an old unit comes off, you need a fresh one before the new AC goes on. That's what this kit is for.

It's built for a top-down install, meaning the air conditioner sets onto the roof from above and gets fastened down over the opening. The four self-drilling screws bite in without pre-drilling, and each washer has its own gasket so the fastener points stay watertight too. Basic hand tools get you through it. If you've done a rooftop AC before, you already know the drill. If it's your first, take your time seating the gasket evenly so it compresses square.

This one fits Coleman TSR air conditioner systems. If you're replacing a tired old gasket that's let water sneak in, or you're mounting a fresh unit and want the correct Coleman hardware instead of a handful of mismatched screws from the parts bin, this is the kit to grab. Using the matched gasket and hardware also means the unit sits at the right height and compresses the seal the way it's meant to, which matters when you're up on the roof trying to stop a slow drip.
