Just reinstalled my ETKA5 so I could look up a few things that have been
looking strange.

One of them is the water pumps for the sink.

According to the ETKA the US had  external pump up thru mid model year C
(82). Then went to the internal pump.  However I have pulled original
external pumps out of 1983 US campers.

Then comes the fun notes on CDN

CDN shows external pump from A-C and then from E to mid J
CDN also show internal pump from mid C to H and then again from mid J
