I will be doing the same and I'm also trying to decide on placement. I was thinking AC in the back over the bed and fane up front but I'm just not sure. I also want to have room for 2-400 watts of solar and maybe a small spot to sit or stand also.
I will like to see what others have to say.

I believe an extended van could have a maxxair in the rear and front, dometic rtx in the middle and 100w panels mounted on each side of the fans for 400w total.

The placement of the ac would be critical, but the middle bay has lots of space between the roof ribs.

Would also require a rack of some kind since the racks extend out over the roof where it starts to slope down in front and gives you more flat space for the solar panels.

I believe most racks for the extended are about 140” in length.

I have some concern about the AC in the middle because of that space. I want supports but not sure how I'm doing them yet as I'm putting an AdWag kit in and need to make sure I fit with that.
I will be using a roof rack.

I am not familiar with the adwag kit, but if the bay between the roof supports is clear, something like DIYvan’s roof support or something similar should work.

@Bazz99 thanks for posting all the pics. It helps. You did a really nice install.

You should be successful in that goal. For what it's worth I've got that same AC, 2 MaxxFans, and room for 400w of solar on my 148 non-extended, (though I'm only running 3 + a cargo box.) I'm using a FVCO rack, and there's just enough room for a 100w Renogy panel on each side of the MaxxFans, with room for the AC in the center:

Are you using the most forward fan adapter/location for your front maxx air fan?

FYI, it appears the Renogy 100w compact panel keeps getting wider. It use to be 19.5" wide and the latest spec is 20.9"X41.8"

Renogy makes another 100w panel that is actually smaller in width, but longer in length, compared to the renogy compact 100w panel. 20.0" x 43.3"

Anyone wanting to use this type of layout, double check your width dimensions.

I am going with this exact layout, but on an extended van, and at first was going to use the flatline rack, but now I am going to use the AVC Rig rack since it is wider and will have more room for the wider panels. 60.25" vs 57.5"
