Hi Craig,
I'm unsure what you mean by "Who knew there was a reduction of hdrm in a sr
van" Please elaborate.
I've read here over and over that tho' simply cutting a hole doesn't leave
the same integrity as a factory version, I've never read any problems with
it. I did consider cutting a 1/2 size hole in a Vanagon roof last year.
(1/2 size = same width but .5 x the factory opening's length). My reasoning
was that later I could double the hole to the factory size if it proved too
small AND it would drastically simply the PT install AND it would elim the
hinged loft issue, albeit at a sacrifice of the kitchen headroom.
Would someone please send me the opening dimensions of a Vanagon Sunroof
opening?
Unless I'm missing something the load bearing issue is N/A with my
'design'. The buckboard I envision would be totally supported by wood
runners along the roof at the edges and cross 'beams' over the roof just
ahead of each pillar, which would not touch the roof. This would leave the
roof simply as it is with the exception of the access hole. The one aspect
I've not measured/determined is whether a 2x6 would be strong enough in the
center to support the buckboard, without fracturing. Does anyone have any
idea how narrow (top to bottom) I can manage to make the 2x6 in the
centerline of the roof before it is risking a fracture? IINM, the high
point of the roof is about 3" above the edges and if the 2x6 is cut so it
doesn't touch the metal that would only leave a couple inches. I need a
mechanical engineer's input and/or a carpenter's knowledge on this point. I
suppose an alternate design would be to use metal. This could be lighter
too. Just weld a platform for the buckboard to sit on and use, as you say,
1" angle iron for the beams. The minimal sag could be mitigated by having a
beam every two feet or so.
One aspect you didn't comment on was my desire to rotate the access hole 90
deg so it allows me to stand in the kitchen area and also allows a real
ladder to be used to climb upstairs. Does this pose any problems I'm
unaware of?
Please/Thanks!
