Ahhh, the Fleetwood Elkhorn... I had a 2001 8S hardside. There's a reason they were nicknamed 'Leakwoods'. As I recall the 8S is for a long bed, I hauled mine on a F250 SC LB until 2014 when I replaced it.
The only aluminum in the "framing" is in the rear section/wall, everything else is wood.
Fleetwood packed quite a bit of features into that little camper. I went on to do dozens of modifications to mine over the years.
In its prime I could dry camp for a week at a time in it. When I was younger I did not mind the climb into the bed area ether.
Sadly the only modification I was unable to do was stop it from leaking. When I got rid of it ($500 scrap) it had a number of rotted spots.
