Our Class C is 27 feet and have no difficulty with DW & me, plus two adult children. We could easily handle another person if we wanted to. We don't tow, so we often use the RV as a car while traveling, and have had little difficulty. The issue with slide outs is complex and often sparks debates. Only you can decide if you want them and the associated weight penalty. Remember, while working out your budget that the tires will need to be replaced at about 6 to 7 years of age no matter how good the tread looks.
Good Luck
