All F53 stripped chassis used for motorhomes from model year 1999 on are equipped with a 6.7 L V10 engine and ODBII. That's the chassis model year, and not necessarily the same as the completed motorhome model year. There were some motorhomes with 1998, 1999, and possibly 2000 model years built on leftover 1997 F53 chassis equipped with a 7.4 L (460 cu in) engine with OBDI. There were no model year 1998 F53 chassis.
Your are welcome to come and check out two here, They are both Fords V10s and model 99 and 2000 and both show OBD1 using Fords and snap on equipment. They both were purchase new, Newmar and Fleetwood.
Where is the OBD port located? Can you post a picture of it? The OBDI port is completely different from the OBDII port.
My 99 and the 2000 ports are OBD2 our computers are OBD1. Port are located below the right knee. I have own it since new and It has been work on by Ford and at one time I had a letter from Ford stated that it was a OBD1 system on a 99 chassis. Had something to do that they were allowed to use up the old system to get them out of the system. I assure you I check it out with Newmar and DOT.
