I have to agree on both points! We saw great views from the camper in 2019 (and it's not one of the slow ones, and I use wing mirrors, so didn't hold anything up!!) but the idea of taking an SC would be (realistic) motoring heaven!
It's interesting to know how pleased you are with the RX, ironically I'm looking at one of those as a replacement for the LS in a couple of years time.... I usually have one practice estate/SUV and a saloon, when I bought the ISF I thought I was replacing the LS, however I was 'instructed' that my ex police V70 T6 would be going as she loves the passenger experience of the LS!
