I think @lemniscate nailed it. If that cabinet is truly the only place to store the sealer, then I think rolling it out to a better work area is the way to go.
The ways I use my sealer, I cannot imagine carrying bags from the kitchen counters into some other room, and then using it in a cramped space.
Just my 0.02 American dollars.

Finding one the same size that is on wheels might be worth the effort.
This is a pickle, good luck.
