Best Ebb Flow Setup, Ideas?

Just did my first hydro setup with an Ebb flow system. It went so-so and looking for some ideas to improve next one. Was considering doing Drip Hydroponic System but anyways.
I had 2 plants in a large construction mixing pan on top of a large storage container with 10 gallons of solution. When plants got larger it was hard to move to get the water changed, tried different container but was still tough. Whats the best way to put reservoir and pan to get access to change water? Also though on putting reservoir next to the system and have drain in tubing from the sides? I want more than 2 plants going ! What containers do you use?

And tent is about 6 ft tall. If put try on table, it became to high up with lights to be far enough.
