Hey guys so I'm just about to put in my flooring tomorrow and there's a hole in the front right side of the bus above the diesel tank that had a metal panel on it originally.
My question and concern is: Will I ever need access to this hole for any reason? Should I cut a hole through my insulation, subfloor etc. to have access to it? Or can I just seal it off and not worry about it?
Here is a picture of what I mean
Any info on this would greatly help, as my time to work on this is limited to the next couple of days.
