We owned a 93 Safari with the Oshkosk Chassis -- The Safari was built very good -- However the turning radius of the Oshkosh was not very good-- The brakes are hydraulic, not air -- Probably no engine brakes & no air bags -- Rough riding - The good thing is you will have no air leaks, because there is no air system on the coach -- The paint Safari used was the best on the market & the sides are aluminum -- Cabinet work is great -- Over all we liked the Safari -- Had it for two years & traded it for a 96 Safari -- The hydraulic brakes was not a problem -- The 96 also had hydraulic brakes but it had a Magnum Chassis -- The 300 Cummins engine is mechanical & that`s not a bad thing either -- That it for a test drive, & pay attention to the turning radius -- That`s really the only thing we had a problem with -- Bill Willard
