Kieth,
It normally runs a little hotter under heavy load going up grades. I may have been a little slow on my downshifting curve but I don't think so. I think that super fast heat up was a result of failure of either head gasket or cracked head. I have only seen amber warning light 1 other time about 4 years ago after we first bought the coach. it was going up long grade to Yuma on I-8. After that I got new radiator & thermostats. Pretty much cured heating problem except for very long hard pulls then just had to drop a gear orso to bring temp back in line. I've always tried to not get over 215. Just gear back & cool down to +/-200 then back to D. Good signs so far, heads are dry ( no oil or water seep at block/head interface), no other fluid hemoraging or leaking anywhere, radiator & hoses all appear normal & in good shape, oil in crankcase is not milky so water was not emulsified in it as would be the case had it run for any length of time with water getting into oil side. They are going to drain & pressure test on Monday as well as pull air box covers to check for any cylinder scoring. I do want to try and get an audible over heat alarm installed though. Something on the order of an extremely heavy Scottish brogue screaming " For God's sake Clint, she can't take anymore!! Her dilithium hybrid crystals are going to fracture!!"
