I did my first test drive of diesel pushers last month and I've got to say that the air brakes were unnerving. I've been reading posts and manuals to understand the system but I sure didn't get used to the amount of foot pressure required during my short drives. I'm guessing I didn't have my foot fully on the pedal, but rather was resting my heel on the floor like I do my car. I did go ahead and order a 2013 Ventana and I'm hoping that the learning curve won't be too steep. Maybe I should start doing more leg presses at the gym....

They shouldn't be that hard to press. Mine are not that much different than my car as far as pressure is concerned.

I agree, I have no problem with the pressure. Make sure your foot is positioned correctly. Most complaints are the opposite, say they are too sensitive.

The big adjustment is that there is no feedback through the pedal. Very few states have any requirements for license endorsements for air brakes below certain GVW, check with your state BMV, don't take the word of a dealer.
Here are a few links to information you should know.

Ditto on the pressure comments. One thing which may have caused an issue is the design of the brake pedal. At least on my Freightliner, the brake pedal is designed a bit like a "seesaw" with the fulcrum a few inches up from the floor. If my foot is positioned like it is in my auto, it can result in me placing much of the pressure on the lower, fixed portion of the pedal instead of the upper part which is where the pressure is effective.

Good luck and congrats on the new rig.

I agree, though they have a different feel unlike an automobile power brake. Now if you want to talk about pressure to stop, try a Provost conversion. You need lumberjack boots to get them to slow down. I think they are right at their maximum weight for brakes designed for lighter loads of that of a regular highway passenger bus.
