"We like the easyness of our TC and we think 30" is not easily parkable
Just any ware...?"
Once you get above 26' in Class C there will be a huge difference vs what you were used to and obviously liked about your TC. There are lots of choices but adding 4 - 6' really does not bring that much benefit if you don't need all the extra interior space.
It depends a lot on how you plan to use the rig. We spend about 13 hours a day outside retreating to the rig just to eat and sleep. For us the drive/parkability of our 24' 6" C is priceless. We can easily shop, sightsee and park just about anywhere we go and we definitely will fit in any site.
Our non slide Nexus is 101" wide and has a full 7' of headroom throughout the coach making it one of the roomiest 24 footers out there. Marry those dimensions to a great floorplan and we have found what for us is the perfect coach. We have far more storage and payload than we can use and the V-10 powers our E-350 chassis without even breathing hard.
After 5+ years and 52K+ miles, we would never go bigger... just no reason to do so.
As always... Opinions and YMMV
