AWWWWW Where's your "sense of adventure" ??? This is a perfect companion to "I never tow with water" or "A towel soaks up the leak, no need to fix the roof" or better yet, "Just one more trip on my TK's and I'll buy new tires in the spring".......
It's either replace the motor now or make sure you've got a few clay flower pots to sit on the stove burners when the furnace stops working... That usually happens on the furthest from home trip on the coldest day of the year...
But then, if you're "really lucky" wait another season and then find out that Atwood stopped selling parts for your furnace and you'll need to spend $650 for a new furnace because the motor is no longer available.....
