I do have both Firestone and AirLift air helper springs available for a 2022 Ram 4500 and they are both great option, but only one is drill free. The Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers part # AL88255 offer a completely bolt-on install so this is what I recommend because the Firestone Ride-Rite Air Helper Springs part # F2404 require drilling. view full answer...
Demco makes a special version of the Recon hitch for flat bed applications that have recessed balls actually! So what you'd want instead is the part # DM8550046. This has a shorter overall height to make up for the additional height of the flat bed truck and has the portion that attaches to the ball sit a bit lower.
I attached a picture of this installed on a flat bed truck similar ot yours for you to check out as well. view full answer...
For wheels with smaller hand holes like your setup has we know the Wheel Masters 4 Hose Inflation Kit # WM8001-135 would work well. Check out the attached picture and you can see them installed on a similar style wheel. view full answer...
If you look under the dash of your 2014 GMC Savana 4500 RV cutaway there should be a wire bundle held together with white tape. The bundle should be located under the left side of the instrument panel and to the left of the steering column. The wires can be identified by a white label and the color of the wires. The wire colors are (1) Red/Black wire, (1) White wire, (1) Light Blue/White wire and (1) Dark Blue wire and possibly (1) Orange wire.
You will hardwire in the controller as follows:

A standard Bargman 7-Way cable like the 11' part # HM20048 will have a similar quality as the Hopkins equivalent.
If you're wanting something a bit more durable then I recommend the Bargman 7-Way, RV-Style Connector w/ 6' Heavy Duty Insulated Cable # 54006-057. This wiring actually comes with a 1-year limited warranty which initially doesn't sound great but for the world of wiring it's pretty good.

Yes, the Air Lift 7500XL air bag kit part # AL88255 that you referenced is compatible with your 2021 Ram 4500 HD.
For a compressor kit then the heavy duty part # AL25854 will work great to make inflating the bags and maintaining them easier. The compressor will inflate faster than standard compressors and the gauge inside the vehicle will allow you to monitor and inflate them from inside the vehicle. view full answer...
I may have a solution for you, however the custom-fit gooseneck hitches like the Curt # C60626 you referenced will not be compatible with your 4500 Cab and Chassis model. This is simply because cab and chassis models have frame rails that are closer together than standard pickup models.
If the bed on your truck happens to be a flat bed, then you can use the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1500. This heavy-duty underbed hitch is designed specifically for flatbed... view full answer...
I recommend the Firestone Ride-Rite Air Helper Springs # F2404 for your 2021 Ram 4500. These air springs are rated at 5,600lbs which is higher than the 5,140lb payload capacity of your Ram. Do remember that the air springs will not increase your payload, they only assist in supporting the weight with your suspension.
I recommend using the Air Lift WirelessONE Compressor System # AL25980EZ to easily adjust the air pressure in your air bags. This compressor system can be controlled by either... view full answer...
