Hey Lez, at least your 52' is 'on the road.'
If fuel(gas) keeps going the way it is,a Diesel's not a bad idea!
Whatever's under the hood/bonnet, you'll look good cruising down the road.
I was thinking the Mercedes Sprinter engine might not be a bad swap either.
You'll need to be careful with all that
extra HP!

I look forward to the pics.
