I've got a Skylow and the headroom is plenty with my Reimo Variotech bed on rails.
I'd say it feels on par with the van when it was factory. One of the Skyline installers actually said that you gain headroom (not sure how much, if it is anything then minimal)
Had a van with a HiLo for a relatively short time before the van I have now. Couldn't believe how much headroom was lost with that but I guess that's the tradeoff with having such a discreet pop top
For me Skylow is perfect balance of discreet, not obvious vs doesn't cut in too much.
Very happy with it
