The awning was a faff and a half. Fiamma either have the
wrong panel profiles on record, or there are lots of variations to the actual
panels on the vans, or the height and type of rain-seal on the top seam has
changed. Whichever it is; packing
pieces, replacing the kits screws, and using oodles of SikaFlex is mandatory,
or it will bend/deflect, or allow the roof to leak ... quite frankly for the
kind of money you pay for the awning and the bracket kit, I would expect
`more’. All these issues could be partially mitigated if one had full height
workshop facilities, platform stairs and a warm environment ... or half the
cost again to get them fitted in such an environment.
We ended up breaking the job down into four distinct blocks.
For nerds they were:
Day 1 Exposing the inside of the pre-cut and grommeted holes
in the roof (cutting lining and internal ply ... should have fitted the awning
before the conversion ... 20/20 hindsight and all that). Cleaning and abrading internal
and external surfaces to allow Sikaflex adhesion. Laying out the parts, and
testing for size, and then finding the inconsistencies ... and realising that
the two hour job will be no such thing, giving up and going indoors, and then
standing before mirror giving oneself a slap for thinking the instructions and
apparent simplicity were a given.
Day 2 building up the awning to roof bracket external profile
using an industrial lino (usually found on train floors) and Sikaflex 512,
because the brackets were two thirds cantilevered over the side of the van,
with only 6mm neoprene and self tapers to secure them. The self tapers were short of the mark by 1mm, because the
rain seal is so high relative to the groove in the bracket it’s supposed to
live in (however I’ve looked at a lot of these vans, and those panels and seals
are the same `by eye’ on all I’ve seen). If further proof that the brackets are
the weak link was needed; none of the brackets fully extend inwards across the
full width of the accessory attachment points on the van (that’s towards the
centre of the van). That equates to a strip of aluminium missing 10mm x 290mm x
3mm (by design), which as noted above is fuck all material for a lot of money
in real terms.
Day 3 fitting the packed and pre-drilled brackets, bedding
them to the roof with Sikaflex as prescribed in the supplied instructions
(effectively you're making up the missing width in the brackets with super
mastic). Lets just say right now that Sikaflex is an amazing adhesive, and you have to use it all the way through the awning install, it just irks me that to allow full cover of the brackets margin and accessory attachment points you have to allow an additional bead at least 5mm wide. Nipping up all the securing screws and plates with the awning in place
to align the brackets (which in my humble opinion should be a full length
bracket rail, wider than the accessory holes running the length of the roof,
this would require an additional 300ml of Sikaflax to bed, but to be fair
that’s peanuts for the additional ease of fix). Leaving the Sikaflex to cure
over night with the brackets now aligned.
Finally on the fourth day. Remove the awning from the now
set brackets, drill the van panels through the packed side of the bracket (the
cantilevered bit that’s carrying 2/3rds of the 25kilo weight) sealing and
sticking with more Sikaflax, refitting the awning, security plates and final drilling
and fitting of security retaining screws (back of the awning case).
All that’s left to be done now is nip up the nuts after a
few hundred miles.
As above, in a workshop this is a half day job for two
blokes (it’s heavy to lift on and off), and if they can’t expose the pre-cut
roof holes they use retained bolts through the accessory attachment points and
oodles of Sikaflex. However it’s never as solid as fitting the internal
brackets which are made of steel and cantilever the opposite way to the
external brackets.
I’ll drop in the profile drawing, so you can see what Fiamma
says it should look like in an ideal situation.
Mole update to follow.
