G'day Rossco,
I have'nt noticed any blind spots at all, the tyres don't seem to block any light either.
Two are ample for me.
Maybe a small one down at towbar level for hooking up snatch straps orjacking.
I have a reversing camera hooked up to the GPS.
The GPS came with a wireless camera but it was hopeless, I bought a good camera
that is a cable type and is brilliant.
I'll put up some pics of it if you would like to see it.
How's that great setup of yours working out?
Are you happy with the solar setup you have?
Cheers Gavin
