When I removed mine I used a pair of jacks to support the weight as I cut through the supports, then lowered them so I could drive away (disconnecting the power cable first of course
)
I did have one person coming to get it for her new van conversion but she cancelled as between agreeing to get it and the day of collection she got scammed on the new van and lost the van as well as her money on it
So lady really lost out, very sadly and I had to just chop it up to get rid.
