Oh yes, I always thank the person giving information. Knowledge will save a person a lot of grief, esp. when shopping for older rvs and vehicles. Also, it sounds like you might have owned an Xplorer in the past?
Regarding Dodge TBI, I found this at Ramcharger central. com:
"my 1987 came with a factory 2bbl carb. 88 was 1st year for TBI on 318 and 89 was 1st year for TBI on 360. 1992 had MPFI on the 318 magnum and 1993 was 1st MPFI 360 magnum."
I'm a former shade tree mechanic and I surely don't want to have to rebuild an old style carburetor (aspirated?).
I've always liked the older Dodge 318's and 360's. Reliable, at least for me, and the 318 TBI got good gas mileage.
Again, thanks for your help!
