Van Creveld was wrong, given that he cites the Axis as maxed out, but then they jumped in later months to much higher levels than he claimed were possible. The reason that shipping was a bit of a problem given the British interdiction and resulting detours that convoys had to take. They were at much less capacity than they could actually support out of Tripoli, the problem was the distance to the front and getting the shipping in. Tunisia simplified things initially because it was so close to Sicily and could avoid Malta much more easily, plus could even handle a high volume of airlift, which was not possible via Libya.Tripoli was already used to maximum capacity, according to Van Creveld's Supplying War. There won't be a lot of pouring going on.
Also according to him the Tunisian invasion actually improved the german situation: logistics were not such a bottleneck anymore when the harbors in Tunisia were available.
