Mike,
Glad to hear from you!
Roelands point is that- unlike in Bronco's base- Kdo.Ger.40's rear legs do not protrude bellow lowered mesh screens.
This is also visible on the picture you posted on March 07, 2020 in this thread.
I was sent a walkaround of a Kdo.Ger.40 by Carlos Martin(varanusk) and there are also some pictures, proving Roelands point:

Roeland also kindly posted a picture of both bases(DES-Bronco) side by side and this picture shows quite clearly where the inaccuracy in Bronco's rendition came from:

The rear legs in Bronco's kit are mounted:
1.on a position that's too forward, whereas they should be mounted behind the trailer mounts
2.on a sort of outrigger arms, whereas they should have no outrigger arms (leg bodies were welded to the base frame).
I've chosen to build the Kdo.Ger.40 in Bronco 2020 Campaign (that I happen to lead) and I will incorporate Roelands findings in my build.
Cheers,
Angel
