RV: 2006 Allegro Bay 34XB, Jeep Grand Cherokee toad, 8300 miles, GM8.1 on a W22 Workhorse Chassis.
Driving at 60mph on I75 15 miles north of Tampa with extremely heavy traffic, lost all power steering,engine light illuminated and an almost immediate engine overheat occurred. Luckily we were traveling in the right lane and were able to safely bring the coach to a stop. Called Workhorse, they sent one of those huge tow vehicles and within two hours had been towed to a Workhorse Service Center. The serpintine belt had broke with only 8300 miles, cause was unknown.
Workhorse did a great job getting to us as fast as they did and took care of everything under the warrenty with no questions asked and no outlay of cash needed on my part at any time.
Things happen real fast when that belt breaks. Steering that monster without power steering takes a huge amount of effort. If we had been in the center or left lane we could have had real problems getting off the road safely considering how heavy the traffic was.
