Could you not have tried vehicles like Puma, or T0 Raketenwerfer? Neither cost munitions.
I cannot agree; Volks and their panzerschreck upgrade isn't a very high amount, whereas King Tiger cost arms and legs. If anything, KT shouldn't be callable if you lost any of the trucks after deployed.
PS I actually for the better part of WFA's post-release assumed losing a truck meant you couldn't do these things ;p
most trouble i got is against USF. UKF and SU i am fine with it.
right now i found if i go battlegroup by the time stuart hits the field usually i only have 1 shrek and 1 reketenwerfer, (used 1-2 flame nade while fighting infantry) it will just run pass my at gun (or charge from other direction as the arc is so small) and push my AT sq around, shooting my flak HT while taking all the hits from my flak HT like tickles, then infantry blobs follows to smoke or wipe the at gun, deal with my at sq.
if i go mech, then i am kind struggle with ally infantry blobing and their HMGs.
so once my HQ is destroyed i lost shreks upgrade option or puma to fight ally early armors and they can just circle my AT gun to death for fun. since there is no vehicle crippling for OKW, it is pretty much gg.
