Question:

I have a 2021 keystone bullet premier travel trailer. It has a Ge a/c unit. I want to replace it with a 15000 but unit. It is ducted. What unit would be a good replacement?

Hey Nick, for your 2021 Keystone Bullet I recommend swapping your GE A/C with the Advent Air RV Air Conditioner System # ADV64FR.

This is going to be a brand new system that including a new air distribution box, wiring harness, wall mounted thermostat, and will work with ducted/ non-ducted systems. This unit is also rated for 15,000 Btu so there won't be any changes to that.

Hey Nick, how did the swap to the Advent Air system go on your Keystone Bullet? Did the new unit tie into your ducted setup the way you wanted? Your update could make it easier for the next person planning a similar upgrade.
