I have a vauxhall combo and getting ladders off it is easy,the ladder rack is set back on the van so once the clamps are undone you just slide it off.
As for buckets I use ettorie with lids and the floor of the van is rubber.
I will be selling it possibly end of next month so if you have not found anything your welcome to have a look its a 53 plate with 83k on it just had new cam belt,battery and starter motor two weeks ago.
