Coleman Mach RV A/C Top-Down Mounting Kit 48203A1101
Coleman Mach RV A/C Top-Down Mounting Kit 48203A1101 — Product description
This is the top-down mounting kit for Coleman Mach rooftop air conditioners. It ships with the gasket, four self-drilling screws, and washers with gaskets, so you've got the hardware to seat and seal the unit to your RV roof from above. It's the correct mounting set for a Mach install or a straight swap.
The Coleman Mach top-down mounting kit is the hardware that fastens a rooftop air conditioner to your RV roof from above. It's made for Coleman Mach air conditioner systems, and it comes with the gasket, four self-drilling screws, and washers with their own sealing gaskets. That's the full set of parts that seals the unit against the roof and holds it in place.
Most rooftop AC installs go one of two ways. You either draw the unit down and clamp it from inside the coach, or you fasten it from the top. This kit is built for the top-down method. You set the air conditioner over the roof opening, drive the self-drilling screws down through the mounting flange, and cinch it against the gasket. The washers with gaskets keep water from wicking in around each screw. It's a clean approach when you're replacing an old Mach unit and don't want to tear into the interior ceiling assembly any more than you have to.
The gasket is the part that earns its keep. A rooftop AC lives out in the weather all year, baking in the sun and shedding rain, so the seal between the unit and the roof has to stay put. A fresh gasket on a new install, or on a swap, is cheap insurance against a leak showing up over your bed six months later. Reusing a squashed old gasket is how people end up chasing water stains.
Who's this for? Anyone fitting or refitting a Coleman Mach rooftop air conditioner who wants the correct mounting hardware in one kit instead of sourcing screws and gaskets loose. If you're doing a straight replacement, having the right screws and a new gasket on hand keeps the job to an afternoon. Confirm your air conditioner is a Coleman Mach system before you order, since this kit is matched to that line.
One note on what's in the box. You get the gasket, four self-drilling screws, and washers with gaskets. It doesn't include the air conditioner, the ceiling assembly, or a thermostat. It's the mounting hardware only, so plan the rest of your parts list around it.

Frequently asked questions
What does this kit include?
The gasket, four self-drilling screws, and washers with gaskets. It's the mounting hardware only, not the air conditioner or the ceiling assembly.
What air conditioners does it fit?
It's made for Coleman Mach air conditioner systems. Confirm your unit is a Mach system before ordering, since the kit is matched to that line.
What does top-down mounting mean?
You fasten the unit from the roof side instead of clamping it from inside the coach. You set the AC over the roof opening and drive the self-drilling screws down through the mounting flange.
Do I need to pre-drill the holes?
No. The four screws are self-drilling, so they cut their own path as you drive them in.
Will this kit help keep the roof from leaking?
The gasket seals the unit to the roof and the washers have their own gaskets to seal each screw. A fresh gasket on install is your best defense against a leak.
Does it come with the air conditioner or a thermostat?
No. This is mounting hardware only. You'll supply the Coleman Mach unit and any controls separately.
