A lot of parts will be available through ebay etc and the aftermarket. Ram 4th gens are probably the longest-lived truck model in history! There will be a healthy aftermarket for years to come. Engine parts you'll be able to get. What you can't get, you can source from ebay or a local salvage yard. You don't have to deal with rust in your area. Exterior cosmetic items are often quick to be discontinued and harder to find (good) aftermarket. Trim, etc. And they take a beating in your area. Items associated with the driver's door (trim/gaskets/hinges, etc) that get used each time your truck is used.
- Door/window outer belt weatherstrips. They usually get discontinued early and aftermarkets are "ok" but usually inferior to OEM. I bought a pr for my Ram. That said, if yer not too picky, aftermarkets will work just fine. Worn ones can lead to door bottom rot (not in your area though).
- Cab mounts. They eventually get old, crack some, and can sag. Aftermarkets are usually hard and not OEM-like. Get a Pr because usually the rear cab ones fail first.
- Driver's seat bottom, cover. They're probably already discontinued for your truck. If not, would be a good idea to get one. They wear first. If yours is black leather, that gives you options. You could always have an upholsterer replace the worn pieces, and forget stocking one. Aftermarket ones are available, but IDK how good they are.
- Upper Control arms
- Lower Control Arm bushings (Oem are usually better than aftermarket)
- Sunroof gaskets (for those trucks which have them). These need to be OEM. Now is the time to get one if you need it.
- Drivers door hinge assemblies. You could drill out and install new pins/bushings. But last I looked Mopars weren't too bad priced.
- Cam & set of lifters??
- Exterior emblems (although they probably don't go bad in your area)
Where do you stop??
