Hi Joe,
I covered some of the changes between the 2019 and 2020 model (2020 is what I have). I have a hunch you may be asking the differences between the 2020 and the current campers (2021 and soon to be 2022). Off the top of my head, some things that changed between my model and the newer models are:
Platform under dinette to raise feet and create storage cubby
Portable Toilet cabinet no longer has a slide out drawer; just has a swing-out cabinet door
Water tank orientation has changed
Momentary switch that triggers water tank LED to see level
Battery access is now via a slide-out tray (Battery Tray ID – 7.5 W x 24″L x 14″ H)
No more battery box vents which means you can strictly use sealed AGM or Lithium batteries; no vented flooded lead acid batteries can be used
One horizontal 20lb propane tank rather than the former vertical cabinet with room for two vertical 11 lb (though only one was included).
Shore power plug is now a 15amp plug rather than 30 amp twist plug
Extrusions have built in brackets to accommodate side awning and side shower curtain
RV entry door supplier has changed; now has the thick plastic screen as well as bug screen
The drivers side front turnbuckle access has changed from a screw in marine portal to a small door
Outside shower connection now has isolation valves
Cushion stitching and fabric have greatly improved (they are now outsourced).
Water tank and pump access (and formerly battery access) are now via a aluminum lid with stand-alone seat cushion rather than a plywood lid built into that seat cushion.
4th generation of the composite material
Thermal break foam is standard and on both the mid and top extrusion interior
Skid feet are now included and available in different heights for different pickups (rather than stacking livestock mats)
Included roof L track is now 3 short section on each side of the roof rather than 2 (gives more position options for the optional roof rack)
Running lights are still LED but the corner lights are now recessed button lights
No more shore power outlets on the countertop. If one gets the optional inverter, I believe you can still get a 120v outlet on the countertop that is run off the inverter
Redesign/move of the undersink 120v breaker box and outlet so they no longer block access from the right under-sink cabinet door.
Inverter is an option
Molle rack as options
Some things that may have changed, but unsure:
Pattern/color of the vinyl flooring may have changed
Ceiling fan may now come with a built in light (though the standard LED light domes are still installed)
Sink and stovetop model numbers may have changed
I've seen examples on the fridge delete models that now show the REDARC battery manager in a new aluminum box with countertop up on the galley countertop. Not sure if that if only for the fridge delete models or all models.
I've been thinking about getting into a new CAMP-X at Big Sky RV to do some photos of the newer models/features, but all units were sold units the last time I was up there. Maybe over the winter they will get stock units that I can access.
Slide out battery tray (Battery Tray ID – 7.5 W x 24″L x 14″ H) and potentially new floor vinyl color/pattern. I have to say, I LOVE the white/brownish gray wood pattern of my 2020 and prefer it to what is shown in the below image. I would greatly miss my current vinyl color/pattern if I bought a newer CAMP-X or CAMP-HBE, but things like that open to personal preference kind of like cushion color).

REDARC box on countertop (this is a fridge delete model). Not sure if that is really the new home for the REDARC in all CAMP-X or not. Also the new seat cushions with thicker "Marine Grade" fabric. I saw these new cushions in person in a CAMP-HBE and the fabric and stitching are a great improvement over our 2020 CAMP-X. Newer owners will be happy with this.
One can see the closed slide-out batter tray in the image. Above the battery box (behind the panel) is where the optional inverter would be mounted. The water tank LED momentary switch is shown above that.
