Whats wrong with sleeping in a tent or in the car and cooking your food on a fire. Wheres has peoples sense of adventure gone?
Nowhere, but if you've never experienced the joy of mountainbiking from a motorhome/campervan then you wont see quite how good it is.
Chuck bike on very sturdy and easy to use permanently fixed bike rack. (no boot and wobbly fittings to contend with).
Get in, 1 person drives, others cook/eat bacon butties (this may or may not be legal…..)
Get change indoors in the warmth.
Fiddle with bikes (you've got space to carry and entire toolkit and selection of spares).
Ride.
Get back, have a hot shower, cup of tea, more bacon.
Hitch bikes up.
Drive home, whilst the passengers sit around the table drinking the post ride beers.
Tents and estate cars are both good, but camervans are just immense!
