I know you did not replies from those who have not transitioned from a TT to a class C, but this comment may help.
We looked at RV's for years. Our current (at the time of purchase) vehicles could only pull a pop up(tent trailer). We would have needed to buy a truck as well as a tt.
We did not have parking at our home for a large truck as well as as a trailer. We can and do park our 27 foot C in our driveway. Legally.
The wife also takes the kids out in the RV more often than the entire family traveling together. There is an added sense of safety in being in a self contained unit for a woman traveling with children.
Motorhome insurance is less expensive than truck insurance in BC let alone truck and trailer insurance.
We did have to find a different mechanic with room in his bays to work on the motorhome. His work is good, his rates reasonable. His shop is less than a mile from our regular mechanic.
