Well, after posting that our RV guy said we could go another year on our bearings, he called back and said he wanted to look at them anyway. He came out today and did a thorough inspection and declared them nearly "perfect" (hubby said that even the grease smelled "new"). He then checked our solar panel and, after several tense minutes of shaking, pulling, looking at all the installation points, declared that it was quite sound (he did say it helped we had our satellite antenna in front so as to defect the wind a bit ... who knows). THEN he pulled the water heater anode ... yikes! It nearly fell apart in his hands! He explained that with the crappy water a lot of parks have (not to mention our own mineral-laden water), we should be checking the anode every six months. Another lesson learned ... thankfully, before it was too late.
