These things handle great! I'm sure the issue was the incorrect air pressure, especially since the front and rear have different specs. Always check whats listed on the door jamb.
I own the low roof short wheelbase 150 Wagon, and it's handling is amazing. It does not have a rear sway bar.From what I can tell, garagedoordennis and 48woody both found poor handling in the low roof short wheelbase vans. Wonder if the low roof maybe has a smaller sway bar? My mid-roof has virtually no body roll, I have a lot of confidence in the handling. I do feel some drift if there's even a mild wind, but given the massive surface area on the side, I'd say it handles it very well.
