well my luck with this van aint getting any better  !!

had our first really heavy rain storm since i bought it and guess what  ,  the roof dont leak i fixed that  ( as i was told )  , isnt the truth 

went in today to carry on working inside  and was looking at the floor thinking why are all the wood pieces i had cut all together down the kitchen end  and then felt the drips  coming out the  light socket in the kitchen

 so decided to take the ceiling that had been put up ,   by the previous owners ,   ( held up with  screws and staples and liquid nails ) which i was hoping was going to be a next year replacement  job ,  and  and guess what all the wood inside is stuffed  some has been replaced  with new most hasn't

so the question is  has any one replaced there pop top  ?  and if so  how much did it cost  ?  if i decide i  am doing it myself  is there much to it  ie unseen  / unthought of things ?

just dont seem to be making any head way with this brick at all !
