Pop top headroom dimension required

[jiffies]

Hi
Just bought a T25 with an Autohomes conversion in need of repair. I would like a Viking conversion but seem very hard to come by & not affordable. However I much prefer the look of the Late Westies/Dormobile or moonraker which I've seen in my budget. I have a growing family so am thinking the bigger the better. Anyone know which is the largest? Headroom dimensions in the sleeping would be great.
Cheers

I bought a wreck with a respectable Viking top (no interior) to fit to my bus, but being an engineer I've got a bit carried away with the whole project and I'm now going to copy/change/improve the Viking sliding mechanism to combine with an electric Danbury roof (if I ever get my hands on it...) Depends if you're in a hurry or can wait for a bit while I measure and copy. Needs relining though. Has roof bars fitted to carry a top box too. Canopy rather tired if I'm honest.
Interested? It owes me about £300. Could possibly deliver if it isn't a huge distance from M25 J11 area (Woking)
Let me know either way,
Ian
