Is there a distance limit for Scart outputs although I cannot imagine it applying in a motorhome?

A bit of research has thrown up the limitation of 10 to 15 metres. It is unlikely that this kind of distance would be encountered in a motorhome but good quality SCART cable is very expensive. Poor quality cable could lead to all sorts of problems.

Well, if there is any way that you could get a scart lead from the box to the telly you will get a far superior picture with RGB.
It might require removal of the plug at one end and then resoldering back on later.
If it is at all practicable then have a go.
In my earlier life as a TV installer/repairer I used to try to persaude people to go down the SCART route with their brand-spanking new Sky box - often to no avail even after demonstrating the superbly enhanced picture quality.
I am sure the quality of the TV should be just as good using the Yellow Phone lead along with the red and black for the sound. Much easier to work with in a M/H than a scart.
This description really describes TV as it was, but in fact has significance in the age of digital and LCD/TFT/PLASMA.
Red Green Blue
That is how the signals originate on the colour camera, three separate channels.
That is how the signals end up on the three guns of a conventional picture tube.
PAL, used for years in analogue colour TV, transmits a very low resolution colour signal that is overlaid on the very crisp black and white signal.
You really see the limitations of that on the snooker table where it shows as a red fuzzy blob displaced just to the right of the ball it should cover.
Digital signals are encoded/decoded to and from RGB. (very simplified description)
Any TV system that does not have three separate (RGB) channels throughout the chain employs PAL at that stage.
If your TV uses an RF lead between the box and the TV, it is carrying PAL that has been generated in the box and which is subsequently downconverted in your TV, even if it is TFT/LCD/PLASMA.
Similarly, if the connection between digibox and TV is phono leads, PAL is used through one lead and the other two carry L & R stereo sound.
The PAL is carried as Composite Video Blanking and Sync.
Whatever the fancy name, it is not really any better quality than that carried via the RF aerial link.
So, why put up with inferior picture quality when you can have sparkling RGB?
OK, so a SCART plug is cumbersome - blame the French! They had a committee that devised it. We call it by its French acronym SCART, they use the term Euroconnector.
Full SCART leads carry three separate RGB wires, a sync wire, stereo sound wires plus some other stuff.
As I wrote earlier, if it is at all possible to use scart leads then do so and benefit from the better quality.
Not all SCART leads are populated with the full compliment of wires so it is necessary to check.
Again, as I wrote earlier, it might be necessary to remove the plug at one end in order to be able to pass it through small diameter holes.
If you are not fussed about picture quality or cannot be a**ed to faff about then simply use the RF lead.
Incidentally if you want to see what I am banging on about regarding picture quality try experimenting with RF and SCART leads and RGB and CVBS.
A Skybox allows changing between RGB & CVBS through one of the menus.
You can do this at home or in the van.
Just remember to write down everything that you do so that you can back-track to where you started!
