Some one mentioned that the John Deer chassis was the best chassis and that may well be. But! JD gas chassis used a 460 with a carb & 3 speed C6 trany up to 1990. 1991 460 got fuel injection and the same 3 speed C6 trany. NO over drive. Then there is the problem of finding parts for that old JD chassis. Freightliner is some help but many parts are only available from specialty rebuilders. A JD chassis may keep on giving, more than you want.
Most MH on Ford F53 chassis, up to 1997, will have a towing limitation of 3500#.
Most MH on a Chevy P30 chassis, up to 1998, will have a towing limitation of 3500#
Most MH on a new style Ford F53 chassis, from 1999 on, will have a towing limitation of 5000#.
Most MH on a Workhorse chassis, from 2000 on, will have a towing limitation of 5000#.
NO Ford F53 1998 model year chassis were built.
NO Chevy/Workhorse 1999 model year chassis were built.
1994-1997 Ford F53 460 had the latest state of tune, with NO catalytic converter.
1996 Chevy P30 454 latest state of tune with port injection (vortec) Gained almost 50 HP over the TBI system. Sweet!
1996 Fleetwood went wide body (8'6") coach on gas MH.
Winnebago went wide body a few years before Fleetwood.
I drive a 1995 32H F53 Bounder with 120,000 miles on the clock. The chassis and drive train has been almost flawless. The house does keep on giving. GRIN
