Armoured Recovery Vehicles - ARVs?

[Taskforce]

I guess that ARVs fall under the Tank Transport section in-game, in the OOB tool. Was doing a search at Wikipedia and found the following ARVs used during WW2:

Ram ARV (Canada) - Ram chassie
M31 & M32 (USA) - M3 Lee & Sherman chassie resp.
Bergepanzer III (Germany) - Pz III chassie
Bergepanzer IV (Germany) - Pz IV chassie
Bergepanther (Germany) - Panther chassie
Bergetiger (Germany) - Tiger I chassie
Bergepanzer 38(t) (Germany) - Pz 38(t) chassie
Bergepanzer 34 (Germany) - T-34 chassie
TT-34 (Sovietunion) - T-34 chassie
? (Sovietunion) - KV-1 chassie (I know that they existed but don't know their designations)
Cavalier ARV (GB) - ? Chassie
Churchill ARV (GB) - Churchill chassie
Grant ARV (GB) - M3 Lee chassie
Sherman ARV (GB) - Sherman chassie

Also I know that the Germans used at least one captured Sherman during 1944 in France, without the turret, as an ARV.

Apart from that, it must have occured that captured tanks, minus the turret, were put to use as ARVs by all nations during the war.

Problem number one - change the icon so that the turret is invisible.
Problem two - what carry capability should be set so that they are able to "carry" medium to heavy tanks and / or maybe infantry (used as APCs)?

In other words, two subjects in one...

Cheers, Taskforce
