It's been a mixed bag for us. Our current TT has served us well in the last 2 seasons, since we bought it. DH misses the extra space and seating comfort from our previous (much larger) TT, and I miss the larger bathroom and under-floor ducted heating it had, but for the trips we do - usually not much longer than 2 weeks at a time - and the relative ease of towing and fitting it into campsites we like, this one is wonderful! Some relatively minor issues with it that the dealer could not fix.
I think there are always some things we wish were better/different, and others that are just right, or even better than expected. We came to the conclusion many years ago that there is no such thing as the perfectcamper.
