Camping Lingo in different parts of the country

We had friends who had a Holiday Rambler Ambassador which was their "motorhome". When they got a Tiffen Phaeton it was called their "coach". They were insulted when people called their RV anything but their designated description. We had a "tiny camper". After awhile we weren't worthy enough to "camp" with them. We parted ways. Now they have a Keystone Bullet. We wonder what they call it!l
