I would guess there is not Sat dish. There is some help on sorting where one might expect coax to run and info on how to ID the markers on each coax. That is assuming the tape is still there!

This chart is a generic of how things were built. The trick is to sort which items your RV has and then compare your RV to the matching drawing?
One biggie to note is the color code on the drawing which should match up with your coax, if somebody has not changed things too much! Tape wrapped around the coax at each end?

Then go here to find an interactive parts site to find locations of things like splitters! Drill down to your RV, go to electrical and finally down to TV/DVD wiring at bottom of last list. That should get a drawing at left and parts names in list at right.
Find name on list and click repeatedly to make flash in yellow on drawing? OR click on part on drawing to flash on list at right!
To keep an item centered while zooming turning, etc. click on plus sign at far lower left before zooming, then click on part on drawing to keep centered!
Takes a learning curve but nicer than crawling and taking off panels to find a small splitter!
