11x14 Harrison Jumbo model?

I'm in need of a changing tent and would like to here from anyone who has used Harrisons jumbo model for ULF. My main concern is will it actualy be large enough? How many 11x14 holders can I expect to use in one changing session? Any other recomendations are welcome as well.

Okay, so I don't use it for ULF, but I use the Jumbo model for my 8x10. I can fit my film holders, boxes of film and a Jobo 3005 tank on its side and still have some room in it.

As for how many holders for one session, how many can you comfortably carry along with the rest of your gear?

I use the 8x10 model. It will comfortably do 8x10 and below. I also use it for 8x20, one holder at a time. I usually put in the holder and the box for exposed film, transfer the film. Take everything out, reverse the slides, remove the dust, etc. Put the holder back in with the film box and load the film. It is a bit tight but it fits in the back of my car.
