Trying to be helpful regarding the 'will it fit in the garage question' posed by Obsessed. I own a degrading/abused HiLo customized with Cruisemaster Freestyle XT airbag suspension. CM teach to avoid air pressure but instead set the ride height prior to any change in load. They teach a 75 mm gap below the bump stop they provide -- I made a gap stick that allows me to set each side without climbing under the trailer plus separate schrader valves right at each wheel well. I do everything manually to purposely avoid all the complexity that CM tries to sell in AUS (Airbag Man); it's easy however because the gap I use and the schrader for adjustment are in my face when at each wheel.
Hence, you will get 75 mm if use run according to CM specs. I think you can get more, however.
If I needed more squat, I'd make a two-part bump stop: one part is bolted to the CM as normal, but shorter; the other part is removable (a cap) from the bolted part and is removed when max squat is needed at the garage. The total height of the two parts would equal the height of the CM bump stop. Additional squat would not have any negative impacts on the bags -- but explaining myself would take paragraphs that I don't want to write unless there's interest.
CM Airbags change everything -- they are just as important offroad as a tongue that provides 90 degree jackknifing.
