2005 Ford F-53 Motorhome Chassis
Reliability tier: verified - see /disclosure/
Engine: 6.8L V10 (3v) (Triton, 6.8L), 3v
6.8L Triton V10 (3V SOHC non-VCT, rated 362 hp / 457 lb-ft per Ford Authority and Blue Oval Trucks from 2005; a 2016 spec listing and RV Business (2019) give the outgoing F-53 V10 as 320 hp / 460 lb-ft, so the chassis rating by year is not settled) on the stripped chassis; TorqShift automatic. MY2005 caveat: one owner record notes a cancelled 2005 F-53 program while the 362 hp spec is confirmed shipping for MY2006 - verify the head by the engine build data before ordering 2V-vs-3V parts.
