I have two currently:
'90 Ranger Supercab 4x4 2.9, M5OD-R1
'99 Explorer V8 AWD with an auto (yucky)
But, I've also had:
'87 Ranger 4x4, 2.9 5 speed
'97 Ranger Supercab 4x4, 4.0 5 speed
'01 Ranger Supercab 4x4, 4.0 auto
If I had more space for parking I would probably also add:
'93 or '94 Ranger Supercab 4x4 4.0 5 speed.
'83-'85 Ranger 4x4
and probably something 2wd from 98+ to put a 5.0 in and lower it to make it a street truck, can't live offroad all the time!
and another 98+ but 4wd so I could put the drivetrain from my Explorer in, and also lower it to make another street truck.
and I'd probably come up with a few more...
...I need more money and time and space, etc.
