This may be very slightly true but I was surprised at how similar in size the two vehicles are as we parked the Cali alongside before we purchased the Autocruise and the difference is around 1m . Speaking to other AC owners, the only problem will be height restrictions which does not both me at all as we never use multi storey car parks or the like, you also see plenty of these in supermarket car parks so no problem there.
Don't get me wrong, we tried everything to stay with the Cali but the toilet/bathroom swung it for us. It will be so nice when wild camping having a pee in a proper bathroom in privacy and then have a shower again in my own bathroom with hot water - bliss
Oh yes, the wife plans to make hot croissants for the morning in our oven
Sadly none of these things we could do in a Cali
