If your bus hadn't been a camper it wouldn't have been topheavy. My
75 Kombi handled really well with its 100+hp 1916 Type 4, and could
easily have taken plenty more power. I drove it really hard on twisty
roads.

A stronger engine is always useful... for getting into gaps ahead in
city traffic; for hills; for overtaking on the highway. You don't
HAVE to hoon on the twisties (never a good idea in a camper, with the
unbalanced load of its fittings).

But for those with a noncamper, you can have a ball on bends... the
stock suspension is for sure up to it.

The convertor may or may not have details to sort out after the
conversion; some do, some don't. However those on the Subaruvanagon
list almost all swear by their conversions, even those who have had
problems consider it well worth the effort.
