We took the 92 mile bus ride into Denali National Park in July. Loved it.
However, the tour bus was on a Freightliner chassis and the pull/push switch for the emergency brake was on the center console in what is normally the radio area. The bus stops on several occasions and the passengers disembark after the driver steps outside. I'm thinking that the bus would go where it pleases if a passenger bumped the E brake switch. Some of the stops were dangerous if the E brake switch was disengaged.
Would that make you nervous? On my MH, the switch is left of the steering column and difficult to hit accidentally.
Or is this the wanderings of an overactive mind?
