Re: [a/s] '97 GMC Suburban

[NEWTOJM@xxxxxxx]

We pulled our 31' with a 1986 3/4 ton suburban for more than 50K miles.  
Great towing, but exhaust manifold problems were a pain (though covered by 
warranty).  Manifold would heat up when pulling long grades and then cool 
rapidly on the downhill side, causing the studs to break, manifold(s) to 
crack, etc.  Replaced one side or the other about every 6000 miles.  This was 
a carbureted engine with Calif. emission controls, which may have impaired 
the internal fuel mixture control.  Newer engines with injection and 
computer-control engine parameters should be much better.  I averaged 9.3 mpg 
towing and 9.8 solo.  Good Luck!
