Obviously, this discussion deviation (convert trayback to tub) would have been better under its own heading to avoid misunderstandings.
HI UNinfromed,
Keep in mind that many tub-backed LRs have been converted to tray-backs because lots of users would prefer a tray to a tub.
You will be up for a lot of two person work including at least undoing, and probably removing and replacing, the roof, (to remove the rear cab wall), if you want to convert to a tub. The tub is even better handled with 3 people.
And then there is the problem of aligning the tub and doors....
IMHO a 109 tub is never going to look right on a 110 unless you do some skilled panel work around the wheel arches (just cutting through the corners of the 109 tubs's "toolbox" lockers will be a headache that anyone can do without).
That is why I
previously suggested getting a 110 tub from somewhere (even one of these perentie wrecks that they're selling).
Also a lot (maybe all) of 109 tubs and ex mil 110 tubs will have the fuel filler behind the drivers' door.
Where is your fuel filler now (?) and have you thought about how you will fit a replacement in the tub and what you will do about the 109 fuel filler assembly?
All in all - it would substantially simpler to sell your tray back and buy a perentie & fit a ute cab if you must (by removing the ROPS fittings)
You can even extend it !

There's plenty of perentie style 110s for everybody you know, and you
even end up with the fabled 4BD1 engine! (which seems to be highly regarded in this section of the forum :D )
Hope this helps you make a decision :)
