WILDRTEXAS, sorry can't seem to find the link to the post with the diagram. I'm not that far along on the Safari. I'm still working the shell and floor. But I did take out the wing windows in the Safari in anticipation of having a bed up front.
I don't recommed it for an Overlander. The problem with putting anything across from the galley in the shorter Airstreams is that you wind up with a narrow bed or a dinette with a 12" wide table (unless you put a counter with bar stools along the wall). But you have to do one or the other in a Safari if you want a permanent bed. So if you put the bed up front in the Overlander, you get a squished dinette.
One successful arrangement like with the bed up front and dinette on the side is BLU_HWY_LADY's Safari. She elevated her dinette over the wheel well so you can sit facing each other across the table.
You might look at the 2007 floorplans
for ideas, if you want to go for it. MEL
, one of the moderators, posted a link in one of my threads to a bed-up-front arrangement, but the link is now broken. Maybe he can help.
In the Overlander, you can put a double bed one side and drawers and desk
on the other, all aft of the galley. The drawers and desk can be fairly narrow, like 18", which allows for the passageway and bed opposite. Then you can have either a gaucho or dinette up front. That's what I did in my Overlander.
