-> TW> I have two Subaru's and ht Chev S10 Pickup.

-> Hm,  I would guess group 25 or 35 for the cars,  maybe 24 (cheaper),  and a 75
-> or 78 for the pickup,  though possibly a 70 would work in there...

 Group 35 and 75 is what the Charts recommend. All there are still in
good shape so I haven't checked out "Additional Fit" sizes yet.
