Not sure how it is with your truck, but my RAM 3500 only had 1 pressure recommendation and that was for max load. The ride was pretty jarring at first. So I experimented by dropping the rear axle PSI to match the front axle at 60 psi. Vast improvement in empty ride. So now I've dropped the front to 55psi and rear down to 45psi. It rides as well as my 2010 F-150 with Bilstein 5100's and goodyear duratracs installed. So I'm very happy with the ride now. I also carry a decent air compressor around in case I get asked to haul something of any significant weight (rock, soil, etc...). So no worries if I end up driving to the home improvement store and having to bring something back that's heavy.
Your front tires will be worn out in no time with that low of pressure on the front with the heavy Cummins up front.
You have the 45 rear part right now air up to 72 in the front. The ride won't be much different and your tires will last.
If a 150 ride is more important than disregard the above.
