What trim level is it...Tradesman, Laramie, etc? I have a Laramie that I ordered with bucket seats and wish I would have gotten the 40/20/40. Every once in a while I would like to move around and rest my foot on the transmission hump. Other wise the interior is fine. I would pass on the auto level. I have the same concerns as you on the air bags. Been there with a bag failure on a Class C. I have 3.42 rear end as it the only choice with SRW. Given a choice I would go 3.73. The 3.42 works good with my Bigfoot and pulling 12,000# 5th wheel. I have the Aisin as well. It's an expensive option but I'm glad I have it.
The 4:10 gears give the highest GVW rating (14,000 lbs.) on the RAM 3500 DRW Cummings/Aisin and highest payload. I test drove one last week and the tach showed approx. 1800 rpm @62-63 mph in 6th gear.....certainly not spinning the engine very hard. My current Duramax/Allison 4 speed OD with 3:73 gears pulls that same rpm at the equivalent speed. Gotta like the new technology. I would go with the 4:10s......
