I have been wondering how that project was going. Thanks for the update. I assume the side sill that you refer to is the gray plastic trim piece that you cut away, and I can see how the bottom lip on it might hit the hinged plastic lid of the LP box. Is it the bottom lip of the plastic piece that hits the lid of the LP box? If so, I might be tempted to trim that bottom lip, but perhaps that trimming would show too much??? Can you please elaborate on what is ‘temporary’ about the spacer that you show. If i understand your explanation correctly (and I may not), then you are needing permanent spacers.

I’ve been doing some more measuring before I start my cutting and drilling… On mine the bottom of the generator is only 1/2" higher than the bottom of the LP box and the bottom of the generator exhaust pipe bracket and the bottom the generator resonator I installed is only 1" higher. So raising the LP box by the 3" only gains me 1/2" before I hit something else. So I am re-thinking the project. Seems like a lot of work to only gain 1/2". Is your next-to-hit place more than 1/2" higher than original location of the LP box?

First off… Now that I am almost done with this… this is a very easy modification… You just need to take your time. And the only part of it where you need to be careful is with the bottom cut as you get to where the quick disconnect port is.

If you do not use spacers the black cover from the LP assembly will hit the sill and not allow it to close completely… here take a look (exaggerated condition since I could not hold everything in place while taking the photo, but hopefully you get the idea).

By temporary spacer I mean that I want to buy some 1/2 aluminum stock to sandwich between the plates instead of what you see in the photo. It was suggested that I do that to make it a solid install… using the spacers you see in the photo could lead to fulcrum reaction when pressure is applied (or something to that effect…)

As to raising it that additional 1/4"… I just wanted it to be as highest as possible with this approach… unsure of what else will hit first after this… I know that the next thing I need to look at modifying is the exhaust of the generator… need to relocate it…
