I looked at those a couple years ago and the cost was
$$$$$$$$$$$$$$$$$$$$$
At the time I was recovering from my stroke/s and had sold the big rig, so we were definitely in a bind.
$$$$ were at a premium as well.
We own a small car hauler trailer so that was a plus.
I scrounged up the dumpster from a manufacture an hour and a half away for $300 as it was made wrong and the grab anchors that the truck gets hold of were in the wrong place.
They deemed it too costly to repair, plus the figured the patch up would look ugly and anyone buying it would balk at the normal price.
This one was clean, never used too.
Tarping outdoors is going to present issues due to the very wet conditions and the temp changes will cause sweating inside the can.
The shells have some nut meat pieces and with dampness this stuff will mold YUCKKKKKKKKKKKKKKKKKKKKK
This stuff must stay dry.
We have thought about a 3-4 yard holding area/room in one corner of the basement and gravity filling it through a window.
It all gets $$$$$$$$$$$$$$$ AND DEFEATS the initial cost of KEEP IT CHEAP
We own the trailer, dumpster and the barrels were dirt cheap when we originally got them back in 92/93 season
WE have explored augers and vac systems to unload, but it all gets into $$$$$$$$$$$$$$$ quick.
I am mulling over a drop gate in the back side at the bottom of the dumpster to allow us to fill a 5 gallon pail quick and then dump that into the barrels.
This would make the transfer much faster than bailing it one 3 gallon bucket at time and pouring it into a barrel.
Time is a pretty cheap commodity when you are retired ya know.
We are always looking at a better way.
I have thought about a 4 or 5 inch auger to put into the dumpster at the bottom facing back ?????????????????
