Hey Jon,
I have fed the curtains through as you describe. The problem is, with the blackout, they're so bulky and don't sit right.
Bus is coming on well. fitted door and sliding door seals, got the pop rivets out of the bunk (that was a nightmare). I shall fit the new bunk (yours) with self tappers (much easier). Also took the amber inserts out of the front indicators and have got a mate (DeluxeDude) to buy some amber bulbs from Big Bang. It's all good!
The steering box................ not sure yet.
Bought loads of camping equipment today though;
double hob cooker with grille
table
folding water butt
cooker stand
mallet
wellies (for vanfest)
(my new credit card just arrived lol)
next on the list is deluxe trim (don't tell Clare).
Apart from the steering box (a biggie I know), we're good to go.
Cheers
Si
