Jerstw,
Great build. You and I are on a pretty similar build right now. I have a 2017 RAM 2500 crew cab diesel, as well. Went with ARE z-series topper, Method NV heavy duty wheels (18") and Toyo MT tires in 285/75/18. I am torn on 2 items at the moment which you have done/are doing:
1) Bumper: AEV vs. the ARB. I love the styling of the AEV, but it concerns me a bit b/c of the lack of protection on the intercooler for the new rams and it also doesn't have bull bar for additional protection like the ARB (or other offerings i.e. RH, etc.);
2) Suspension: Again, the thought process and design behind the AEV is interesting, but at the end of the day you are getting modded Bilstein 5100 shocks. I am concerned about ride quality for the price of the system. I think I will wait and wait for a long-term review from you and others before I make a decision as I am not a desert racer and mainly log long miles on the highway to get to light offroading for hunting/camping, etc. I believe Thuren can get me exactly what I want, but it will be pricey.
Two mods I recently did that were cheap (relatively) and very effective: (1) AEV mudflaps. Work great. (2) Baja Designs fog light pocket kit for the Ram 2500. I mounted 2 squadron sports in each fog light pocket. I opted to put them on a separate switches. The light output on these cubes is amazing.
Looking forward to the rest of your build.
