Just a bit curious if this panel would be usable in a std RV situation....  |

It's a household panel and yes, you can, but you'll need a controller specifically to suit the higher voltage.

Thanks Gerry. I spotted it on one of the FB sites and thought it may be worthwhile for someone.
It's in Dandenong (Vic) @ $57, the price sounds right.
The front is chipped but it's pictured connected to a MM and showing 33.9v
What sort of regulator would it need ?

It depends on how old the panel is too Lance as the older ones were pretty heavy
I bought 4 90w panels for $10 each but tgey would be useless on a van or motorhome because of the weight
They'll be perfect for my son's shack in the riverland though

If it works still it will be fine - but you will need a so-called MPPT solar regulator that accepts up to about 50 volts (most do).
It is simpler (with an RV) to use nominally 12 volts solar modules - but it pays to buy a really good one as their efficiency varies vary from 12% to 20%. None is cheap.
The above matters because an RV has limited space for solar.
