I had the same problem - reinforce(repair) the panel -had to patch trashed area - used fibered filler to patch holes and stiffen panel along with a bit of cheapo resin and glass cloth. Reinforced other side with a piece of aluminum.
I had the same problem.
But now it's much better - I still remove the dog house and back floor panel when I winterize... I put mine back during my first run of the season after I check the shaft log for drips.
I hate taking it off - but as I long as I have it off - I keep it off until I run again.
