Not a panzer IV "expert" and dont have much reference on interior development (how I wish Panzer tracts did an updated Pzr IV series ... so badly needed, and I hope they have found a sucessor after Tom Jentz R.I.P.), but I dont see any major issues with it .... considering its only going to be whats visible through the hatches, but will depend on your own demand for accuracy.
The Trumper kit is based on a late ausf.H or early J. There are definately differences related to what changes were visible on the outside, like hatches, front superstructure profile, pistol ports, vision ports, armament size (the bergepanzer probably doesnt have anything for the fighting compartment), turret traverse, and althought the Maybach engine remained the same, the transmission changed during ausf H upgrade. The SSG 75 transmission was changed to the late Panzer IIIs SSG 77 transmission ... I dont think there is any big visible difference here (?).
So basically use everything thats supplied with your D kit and add the rest from the Trumpeter interior and you´ll go a long way. Of course there are lots of minor details not included in either kit, but my knowledge doesn´t go that far. Hope this has helped some.
