Swapped 865s for 863s little more stink bug but rides great. I think I was bottoming out before on the 865s and with all my weight I really needed 863s
also added a LRA 40 gallon main tank
Every 200 series LC has KDSS. All LX570s have AHC- hydraulic suspension. Both are great- KDSS is less maintenance but the LC holds its value more than the LX.
Buy the newest/ lowest mileage you can comfortably afford….
If towing a lot, consider the LX.
