There are of course other issues to go into, but this is just a very obvious "quick" thing that can be pointed out.
However, this doesn't quite work with the gas vans since the witnesses apparently do claim red corpses for that (although not for Chelmno).

So the witnesses for the gas vans apparently got the color of the corpses right. However, one consistent theme of the witnesses for the gas vans appears to be that they were hermetically sealed.
A frequent claim made in witness accounts which is not listed here is that the “gas vans” had a hermetically sealed or airtight cargo box (see e.g. The People’s Verdict 1944, pp. 8, 17, 50, 65, 85, 89, 110; Kogon et al. 1993, pp. 53, 57, 59; Beer 1987, p. 403; LG Stuttgart, 8 Nov. 1949, p. 239; LG Wiesbaden, 24 Mar. 1952, p. 354; LG Karlsruhe, 20 Dec. 1961, p. 100; LG Bonn, 30 Mar. 1963, pp. 230f., 277; LG Koblenz, 21 May 1963, p. 194; LG Frankfurt/M., 12 Mar. 1966, p. 344; LG Hannover, 7 June 1966, pp. 616, 619; LG Stuttgart, 15 Sep. 1967, p. 565; LG Kiel, 11 Apr. 1969, p. 33; LG München I, 15 Nov. 1974, p. 287; LG Berlin, 14 Aug. 1978, p. 500; LG München I, 19 Dec. 1980, p. 251; interestingly, the verdict by LG Darmstadt, 18 Apr. 1969, pp. 93f., speaks both of an airtight and a merely “almost” airtight cargo box).

The 2 forged letters for the gas vans also indicate a hermetically sealed setup.
Furthermore, I ordered to keep all men as far away from the van as possible during the gassings, in order that they will not be harmed by possibly escaping gases.
The Becker Document (501-PS)
By referring to “possibly escaping gases,” the author once more confirms his underlying hypothesis that a proper operation of a gas van required as sealed cargo box, as this phrase implies that under normal conditions of the gassing operation no gases escape near the vehicle. But as already described in chapter 1.3.2., an engine whose exhaust pipe is connected to a sealed cargo box will bend and eventually blow the box apart. Hence we have a physically or mechanically impossible claim here.

The other experiences made so far let the following technical modifications appear to be expedient:
1.) To allow for the rapid inflow of the carbon monoxide while preventing excessive pressure, two open slits of 10 cm × 1 cm [4" × 0.4"] are to be located in the upper back wall. These are to be covered on the outside with easily movable hinged metal flaps in order to allow for self-regulation of any potential excess pressure.
The Just Document
The demand to have two slits of 10 cm × 1 cm added to the rear wall of the cargo box so that excess gas can escape means that at the time the memo was written no such slits existed and that the gas had no other way of escaping – or else the slits would have been superfluous. Hence the cargo boxes would have been sealed hermetically and the gas pressure would have built up inside until the doors were opened; many “witness testimonies” as well as the Becker document analyzed before confirm this explicitly. Nonetheless these boxes are said to have gassed almost 100,000 human beings. In my mind this is a radical impossibility.

All of these points can be found in Alvarez's book on the gas vans if you want to go into more detail. There are as well many other things that can be gone into. The point here being, if you want to do a "quick debunk" of the gas vans, the claims of impossible hermetically sealed vans is the way to go.
