Wow. That is awesome looking!During our marriage we would consult each other and do weeks of homework to replace a broken $300 microwave but when it came to dive gear the only questions on the table if any, were do we get both units at once or test one first and get the 2nd later.
Not bragging just recognizing the problem.
@letterboy storage units are not for us... I already feel bad about not using what I have. Plus I'm sure the items there will also multiply. Sounds dangerous.
The photo below shows what my husband built in the garage for the gear.
The floor drawers have wheels underneath and are big enough to hide a medium size adult (literally)View attachment 603594
We thought the 2 floor drawers for the "old stuff" and 3-4 of the smaller drawers for consumables and spares of the gear we use every weekend.... Ha! Everything has dive gear, plus some in the guest room and shed.
Again... Not bragging just facing the issue.
Forgive me, I assumed by your post you had an over abundance of stuff... You have lots of room for activities in that room. We broke down and got a storage unit for our camping gear after our tent got ruined in the shed outside and we don't have enough space inside, no garage. It is easy to forget stuff in there...
