Oh the joys of acquiring and fitting out a van, I had and old Bedford with a V8 on straight gas, it was sweet, quick and economical. Suggest a LWB van, heaps of room for trips away.
Vans don't have to be slow either.......Slowboat has/had? an L300 I think but not as fast as one of these...
L300 with stock like wheels and hubcaps 10.83 sec 122mph 1/4mile
L300 complete with roof rack/conduit for that quick plumbing job around the corner, drag tyres on 9.66 138mph 1/4mile
Or how about an old Hiace they still go really well, this ones on straight LPG/turbo, street tyres great for that quick dash down the coast after work.
9.9 sec at 138 mph
