Hmm I am just experiencing the same problem as i am installing a eberspacher
heater which has the same mounting points like a (second) propane tank. two
bolts are real steel (in the back), two are plastic. welded nuts on the
floor though.
Would it be ok to just thread a bolt into the nuts from underneath, or do
you guys think that will rip off?
To lift the plywood floor and do it from above i would have to remove all
the cabinetry, right?
