 It's a 72 wagon with the 2 liter. How much weight can I safely load in the back?

No answers..... Well, it can carry 900 pounds including my Wife and I.

Do any of the door stickers say? Namely the passenger door one...

not sure of the weight  but at a carshow last weekend  a person told  me thay packed it top to bottom with just enough room to get in the drivers seat and drove cross country   the only  problem they had was in denver   it did not like the high elveation.

On the door sticker it should have the GVWR, which means gross vehicle weight rating.  You can load it with the GVWR minus the curb (empty)weight. I think they figure 150 lbs per passenger, so 600 lbs of passengers, plus a couple of hundred pounds for luggage, fuel, etc.  IIRC the number is somewhere around 900 pounds.

Years ago when I built my landscaping, my sedan hauled home over 15 loads of flagstone in the trunk and in the back seat.  :o
Each trip was about 600lbs for 15 miles over awful streets in the hot summer.  I weighed about 170, so there was almost 800lbs. 

I do not recommend anyone to do this, but nothing broke or was damaged, less a few more scratches... 

I laughed at the guys with 'luxury' SUVs pulling tiny trailers for 5 rocks the size of hat boxes...

I think the sticker on my 76 says 4 passengers or 600 pounds.
