Should get most of what you looking for in tr1ad thread.
I got the td27 low one (4*2) and it runs almost like a car. Have passenger tyres on it instead of commercial and I find the ride is pretty smooth but still bouncy in the back seat. Once you put 4 passengers in there it sits down pretty nice.
Friend of mine who works ptsc recently told me this riding real smooth, if you had a frontier you would have gotten a real rough and bouncy ride. Told him this is a frontier you riding in
