Bus conversion might be the only ClasA who has roll-over rating, meaning it will not bring fatalities with even smaller accident.
I moved to TC from vintage Prevost who we used when boys were still at home.
The 12' TC with single slide has all the space we need.
We lived in one for few months after house sale and then we spend 9 weeks in another with side entrance- cutting across the country.
When big motorhome with toad gives you luxury, the TC gives you unbeatable mobility for very little money.
Going across the country, we would have problem with long RV in about 80% of places we stayed.
