RAM 2500 auto level rear suspension

True air suspension is always "auto leveling". That is the secret advantange to air suspension in cargo vehicles - steering angles and ride height remains the same empty to loaded.

Our aftermarket Autoflex air suspension works very well with a camper. Empty to 5000lbs in the bed the ride height changes about 1/2" plus whatever the tires sit down. Sway is greatly reduced vs wagon springs and gas shock system.

Loaded steering and braking performance are noticeably better.

IIf this one has the coil spring rear I wouldn't do it for a truck camper. Go the the 3500 with the leaf springs. Lots of ways to modify the suspension there, not so much for the coil springs. It might work for your pop-up, though the better ones of those can be pretty heavy, but looking ahead the 3500 will give you options that you will not have with the 2500.

If you know you will hauling a truck camper in the future, start with the 3500 SRW long bed. You can get a 2500 to the same level as a 3500, but usually it will cost about the same or more than if you had just bought a bigger truck at beginning.

I started with a F250 pulling a 11,000 lb toy hauler and switched over to truck campers. By upgrading receiver, suspension and wheels ($3000-4000), I was able carry a 4000 lb truck camper while towing an 8000 lb enclosed trailer. It did this well but was at 80% of the component limits and over truck manufacturer warranty ratings(even a 3500 SRW would have been over). If I didn't have the truck, I would have started with a 3500 DRW because of the payload and tongue weight requirement (typically 8000 lbs on the rear axle).

We plan to upgrade to a 6000 lb truck camper in the future and knew my F250 would not be able to handle another ton of payload, so I just upgraded my truck. I now have a something that will handle the largest of the RV's when we are ready to upsize.

Check with the guys over in our truck camper forum as they use both.

As 516 says most 3/4 ton trucks will generally have around 3000+ lb for a payload.

One ton SRW trucks may have up to 4000+ lb payloads.

And one ton DRW trucks can have up to 7000 lb payloads.

All depending on how the truck is configured.

It all boils down to how heavy of a camper and how much gear you pack onto your rig when you go camping. The 2500 with a gas engine can have a payload north of 3,000 lbs. Do you tow a boat as well? Or a utility trailer? You have to consider that tongue weight, along with any on board water, clothes, tools, and family/pets.

I would be looking for a nice used pop up.

I wouldn't do it. How many new 2500 Rams have you seen with campers on them? Stick with a 3500.

The payload available for that truck would likely be around 3000#.

If your over weight (TC wise that is) it might be a real challenge to add any more capacity.

Looking at a left over 2014 w/6.4. It has the auto level rear air suspension. Would I have any issues if I get a slide in camper down the line?

Depends on how heavy the camper will be. It is all about available payload.
