Have the garage set in a tool box or cabinet, organized with rails or socket trays as others have shown. Then set up a separate tool bag or tool box for travel, "grab and go". I would guess that you don't typically take all of your sockets, wrenches, pliers, drivers, etc when traveling, and the travel tools could be much more focused.
@RooflessVW has posted his kaizen foam organization before, and it's really slick. Find the right Packout or similar box and that might be the best option.
Packout plate screwed down with 1/4-20 screws and T nuts. I used a peice of MDF so the T-nuts would have something to bite into. I sealed it with some Valspar grip paint on the top and bottom. My two Packout boxes. All is hidden under the factory shade.
