Hi Ive had mine off road quite a bit and its great. Had to upgrade the suspension (2") to give it a bit of ground clerance.
I havent driven a D22 but my last truck was a 97 crew cab Hilux and the D40 is way better than that.
More power, better control and a softer ride even with the heavy duty suspension.
