I have the ltd with reg dampers, i love the ride but if you can, ccd is the way to go. I test drove a ccd equipped expy and navi but a lot ppl on here have the higher trim so they can give u better long term ride impressions than i could. With mine As compared to a new f150, the expy doesnt shimmy as much and not as firm(4x4, the 4x2 models are way softer than the 4x4 models and my expy). With that said, the base suspenders on 20in wheels is still pretty firm. As a whole its completely comfortable, somewhat absorbent, great body control and not many truck like motions come through(uneven body shakes, extra harshness, skip like motions). My biggest gripes with the regular suspension is its inconsistency, and lack of wheel travel, esp in the rear. Sometimes my truck is as smooth as glass and is smoother than almost everything ive driven b4. Then at times you feel every bump on the road. Its not egregious, but on roads with alot of imperfections its sometimes annoying. As far as wheel travel, on uneven roads, it will shimmy and it gets busy at times, more than i think it should. All told, its still one of the better riding trucks ive driven, but it only met my expectations not exceeded them and some crossovers ride better admittedly. Best way to describe is its like a trucky feeling crossover actually. From my tests of the ccd, its feels to me a lot more absorbent, way more pillowy, and more luxurious, almost boat like. A lot of ppl dont like it because its 2 soft, but i like that plush wafty feel. Where i believe it excels is its bump isolation as compared to the base suspension. I describe it as a very high modern town car as its not quite european feeling. In all, as i feel the reg suspension is a great riding truck, the ccd makes it in par with the last gen of full sized lux sedans. For ref, Ive driven a 13 bmw 750li and the ccd was better. Sorry if its wordy, prolli get crap because i always ramble heavy in here esp in regards to driving characteristics.
