Yes the camper is homebuilt . A friend made it about 15yrs ago , he had a '37 Chev then.
After that he had a '46 and the camper saw use there .
I was camping in my truck one summer (in the canvas canopy) and we had 2" rain over night . The bed got wet and I had had enough.
Mean time , my friend has bought and rebuilt a lovely '59 Apache and the camper doesn't fit................
Yep , straight 'round to his place I go
.
