Air Bag Kit for 2018 Thor Gemini 24TF to Level when Slide Out is Out
Updated 12/01/2025 | Published 11/06/2025
Question:
Hello, I have a 2018. Thor Gemini 24tf on a 2017 Mercedes Sprinter 3500 V6 diesel dual rear wheel. I am looking to correct an issue of when I parked the vehicle and extend the slide out it sags on the left side. Do you think airbags would be an option? Just having to drive up on blocks on the left side to raise the vehicle to make it level inside and no longer want to do this. Thanks! Dave

Hey Dave, yes an air bag kit will help level your Thor Gemini. The correct PacBrake kit would be the part # PB79RV. If you use an air valve for each bag you can tailor the amount of pressure needed for each side of the RV so that you can level it like you are wanting. Are you wanting a compressor kit too?
