We used a revo rack on our 2019 road trip to Spain, France, Italy, Austria, Germany & Holland covering 2500 miles in just under one month. The rack was brilliant and easy to remove, & store in the passenger seat/footwell overnight. We carried a small suitcase on the rack.
However, I would tend to agree with some of the comments posted. The case had to be removed from the rack each time the roof was operated which only took a few minutes, BUT!……… it was a pain if it suddenly started raining and the roof was down as I had to get out of the car, remove the case whilst my wife operated the roof, then replace it on the rack.
Also, whilst on the autoroute around Rome, the traffic slowed to a crawl and the temperature was 39 degrees! Because the traffic didn’t come to a complete halt, I was unable to get out & remove the case so we couldn’t put the roof up & switch the air con on. My wife held an umbrella over us for some shade, I’m sure the Italians thought we’d gone mad!
We are planning a trip to Northern Spain & Portugal next June so, we are fitting the rack but not carrying a suitcase on it. We will just use a soft bag which can be folded up & stored under a seat for any food shopping en route to our accommodations as the boot will be rammed!
