I was looking at the AF 1 as well as the M&G for my 06 Wrangler. I chose the M&G to save the installation costs. My MH was already set up with an airline and wasn't sure if that line would be compatible with the AF unit. Either unit would be fine. However, I would caution you about the installation process. On my install you have to pull the master cylinder away from the booster to insert the MG unit. There are two push rod adjustments that are needed and if done incorrectly you will have problems. If your not comfortable with that type of work then be sure to factor in installation costs. What may be easy for some can be a nightmare for others.
