It's all down to personal choice, I would never preach what I believe to be best for any
particular individual, only for myself. I can quite understand somebody setting off for
their annual 3 or 4 weeks relaxation just throwing a certain level of caution to the wind and relying on recovery
and getting someone else, paid or otherwise to sort out any problems. Even if they
themselves happen to be a time served mechanic, gas engineer and electrician rolled into one
with the physique of Arnie.
If you haven't got the skills or physical capabilities then you have no choice, other than as
has been said you carry a few things with you, especially if specific to your vehicle. Numero one IMO
is to have the Handbook with you, the number of times I've seen and had vehicles jacked
on the wrong point by the likes of Quik Fit "trained" fitters! Then the poor old owner drives
off wondering why his vehicle steers different. "You must have hit a pothole mate".LOL
If you own a Boxer, Ducato van of the specific vintage and you suspect it may be a 5th gear failure victim,
it may not be overkill to carry an overhaul kit, if you can get one that is!
