Thanks both, I really was to get out and use it - maybe I'll have to go for a 'staycation' in the drive
It' a CDF 16, so pretty small compared to the units most people on here use, but I don't think you would want to anything much bigger in the Renegade unless you don't want to run rear seats/passengers. It actually takes up pretty much the whole of the '40' side of the 60/40 spit rear seat width, and runs from the seat back to the tailgate. My brother has the smaller CDF11 which travels on the middle seat when he uses it. But when travelling with the two vehicles we generally only use mine and rotate product through it too cool bags as required, and tend to buy fresh stuff to consume each day if possible.
You may be able to fit a bigger model in but this is how the CDF 16 stacks up in my setup.
Control panel almost butts up to back of rear seat and take almost full width. (Only just switched it on hence the high temperature!)
Other end is almost flush with the tailgate when closed.
There's space above to the parcel shelf though.
Not the biggest in side (just <16 litres but you can can get a surprising amount in there if you get rid of unnecessary packaging and don't just fill it with drinks bottles etc. A litre carton of milk shown for comparison.
