Despite what started as a minor Aqua Hot coolant leak in my Western Alpine motorhome last month, the engine coolant hose has now completely blown out three times this week crossing Texas on I-10. Each time it happens, I lose coolant and have to find a repair shop, but the repairs don't seem to be holding up to road conditions and vibration.

The first failure happened about halfway across Texas, got it repaired at a local shop, but it blew again after only 80 miles of driving. Made it to Houston where it failed a third time, and now I'm stuck at Auto Tech Center in Kingwood, TX (owned by Wendel Walden), paying $50 a night for water and electric, plus $225/hour for labor. I'm also facing additional costs of $10 a day to store a box trailer I need to pick up on the south side of Houston.
