Hi Dave,

Sunday, you mentioned that "The smaller pins affected '73 and some
'74 models, but most of them have been upgraded and there is still an
active recall on those that haven't."
Can you shed more light on this, specifically what pins are we
talking about? How do I tell if mine are okay? I have a 1973 Canyon
Lands 230 model. Are you aware of what weak points Bob Brewer is
talking about in the early suspension? Are we only talking about the
air supply system here or something more serious like ball joints, etc.?

I found a weak point in my coach, the radiator. I just pulled mine
to have it rodded out and the radiator shop told me that under pressure
I have many pinhole leaks. Suggest other owners have theirs pressure
checked before hot summer driving . If mine is shot, then I am sure
many others are probably shot too because the previous owner took
excellent care of the cooling system as evidenced by spotless water
jackets in the engine. I had to have mine recored at a cost of $300
which I feel is not too bad and it's cheap insurance. It is a monster
sized radiator so that didn't seem too bad. It should go a long way in
keeping both the engine and transmission cooler running. I did the R&R
myself. It would cost double that to have it all done I think. The
radiator is a bear to pull unless you are in there anyway. I did the
fuel pump, water pump, fan belts, hoses, thermostat and rebuilt the
alternator while I was in there. I stuck with the original water pump
and just had it rebuilt with my core because rebuilts I checked at Napa
had inferior castings and impellers. My rebuilder uses heavy duty
ceramic seals and industrial bearings so it should outlast the
motorhome.
