I have:

Sunderer:

+spawn deployment
+AH60 Mortar for front turret, which is badass btw
+auto repair

I am willing to dump more points in sunderer if we get large parties frequently.

I also have a couple upgrade for the single person aircraft, equipping it mostly for anti ground combat.

For anti air I mainly play HA , and have the anti air rocket. Thinking about getting skyguard for lightning though as it also seems good against infantry.

Wild - whats the minimum elevation on skyguard, can you aim low?
