   Hi Xeno,   
      
   Almost everyone who has posted, is very well known to all of us, Xeno.   
      
   Thanks for that advice, as you've always been very helpful, and observant   
   of details that many have missed (e.g., the specific tire wear peculiar to   
   mountain roads due to suspension forces related to positive camber which   
   drastically affects the outside edge of front tires).   
      
      
   That's a factual detail that has stood the test of time, which NOBODY else   
   noticed, nor could they explain, until you explained it to the rest of us.   
      
      
   Hence, I have reason to admire your factual acuity, where, in this case, I   
   also respect your judgment, and, in fact, the record shows, we were   
   "almost" as conservative as you suggest, where we assumed 25% of the rated   
   capacity in our calculations (instead of 20%).   
      
   It need not be too often stated that most of us (all?) on Usenet are old   
   men, with many decades of experience with automotive batteries (in all   
   sorts of climes around the world).

   Thanks for the explanation.   
   o We already calculated at 25% but we can easily adjust down to 20%.   
      
   At 20% rated RV battery capacity, the setup will last about 20 hours.

   Hi Xeno,   
      
   I consider that comment pejorative; and I tell you so.   
   o Rightly or wrongly, there was a reason for what you called a "diatribe".   
      
   You may need to understand that I take on the tone of the poster.   
   o It's a tactical technique called "mirroring" implied intent.   
      
   The intent is to funnel the poster into being an adult.   
      
   It works well with adults.   
   o There is really no technique that works well with trolls   
      
   Since, clearly, they posted to this thread many times   
   o Even as they were never once fed.   
      
   --   
   After decades on Usenet potlucks, it's clear who brings value to share.
