swapping hi top over - help

[iowcamper]

i have finally managed to get myself a pop top roof to replace my hi top with

!BtK(R9QEWk~$(KGrHqUOKi8EusBo,9d7BL6)td58nw~~_35.jpg

any tips on removing the hi top in place (can be seen on the van in my garage phots) hows it held on etc not bothered about damaging it particularly as will probably smash up and dump anyway

as far as i can see the wooden frame then attaches to the roof (hoping the existing hole will be sufficient) and the whole unit then fits onto this and seal the edges. Has anyone done similar and got any tips, loads of questions like what do i attach the wooden frame with? self tapping screws or bolts etc what tools will i need (any specialist tools), will the roof need any additional strengthening (cant imagine the pop top weighs that much more than the hi top?)

as a complete novice should i be attempting this myself (fairly competent diyer so think its within my abilities) or should i be paying a professional to fit it??

like i say any help would be greatly appreciated, not attempting the changeover for a couple of weeks so thought i better start doing some research now

That looks like an Autosleeper pop top..

it would be better if you could confirm this.. and then pop top sleepers can give you some more info

yes pretty sure its an autosleeper roof, it lifts and shifts backwards and then two hard fibreglass sides flip up
