I'm feeling your pain there @babadec, I've got one that I'm in the process of fitting into my campervan (should have done it when I converted it, but I'm a bit stupid!).
Today I've spent most of the day laying under the van on the road fitting and then removing rivnuts to fix it in with.
I thought I'd be clever and make a frame to hold the heater under the drivers seat floor and then duct the heat up into the living area. So, frame made and holes drilled to mount it, the plan being to use rivnuts through the van floor to make it removable from below if required.
A full day later, freezing my bits off outside and the rivnuts are in the bin.
Sodding things either spin or cross thread! Fitted, removed, cross threaded rivnut replaced, fitted, last bolt spun before going tight, removed and drilled them all out for next size up, fitted, second to last one spins again, sense of humour failure, drilled the whole lot out again and getting nuts and bolts straight through the floor tomorrow!
Not my finest day and currently wondering if its actually worth the hassle.
