Forget the "towed" stuff, just order up an M7 Priest, M3 or SdKfz 251 w/ any of the various cannons, or any of the various German self propelled artillery. If HTC would unleash some of the "amateur" modelers using the existing chassis already in game, the number of quality (see re-modeled/upgraded) gv's in AH would be 3 fold.
