Help! Fish finder interpretation

[TubeDude]

Hey Pat. I was just wondering. Dangerously thinking. What haven’t you tried to mount on a tube? 

Been tough to mount downriggers.  Every time I try to screw or bolt down the base plate my tube goes flat.

Otherwise, there ain't much I haven't tried or don't currently use.  Just like a mini bass boat...only everything within easy reach.  Oh yeah, I have a tough time getting up on plane with my 40# thrust MinnKota.
 

Here are some pics of current and former mods.
