no worries gaz
with the flat there is still enough room for two hozereels, bucket ,etc at the back
(front as you open rear doors)
I had mine fitted as far forward as possible i.e. behind seats
Also there is still room at the sides (as you open side loading doors for buckets, tool boxes ,etc.
The other thing I did was put two bars across (side by side)
they are about 12-18 ins from the top of roof and they are perfect pole carriers
Can send you pics tomorrow if you send me email address
