We have a 1998 National Tradewind with a Cat 3126 engine and Allison MD3060. The MH has 30k miles and I never had an overheating problem. Recently on our trip from Florida to New England I stupidly had it in the econ mode on I-64 in Va when the alarm sounded the gauge was in the middle no where near the indicated red hot area. After stopping 2 or 3 times we got to the top and made it to Winchester VA keeping out of cruise mode. We got to a CAT repair and they could not find anything wrong. Continued to PA and it alarmed 1 more time, pulled over and it cooled down and we continued. The remainder of the trip I manually shifted down a gear to keep the RPM's between 1600 and 2000. I had a slobber tube extension installed a couple of years ago, but how can the radiator be cleaned? Thanks Bob

Brett: Thanks for the lead, Gaffney stated the problem is in a module that needs to be replaced at an estimated cost of $12 -15k. I am going to find and install a GPS driven speedometer odometer. Bob

We purchased this MH in 2008. National Tradewinds Freightliner chassis and a Cat 3126 300 HP. The odometer registered but when the ignition was turned off it reset to 9596. The trip worked fine and that is how I keep track of miles for all maintance and fuel economy. Recently the trip odometer locked up, it could be reset but stayed at 0 but after a short stoppage it worked again. This whole scenario repeated and included the speedometer. The last time I drove it all worked. Any ideas Thanks Bob
