There is a good bit of difference in the 01 Knight and the dip but the newer Knight and Dips are pretty close. Here is a little info on the 01.
The 01 Knight with the 260 engine comes with a T-1000 4 speed Allison, you could
order the optional engine package with the Allison 3000 trans with the 300 ISB
and 315 ISC the chassis is a 4 air bag and came with a propane Gen, Diesel was a
option, the coach came with air over hyd brake system and I believe that system
had some problems and if I am not mistaken it also came with the aluminum
radiator that was bad about parting and getting coolant in the Allison trans and
that could have been changed out. Also there was a recall on a bad suspension
problem just not sure the 01 was involved.
