Buzzy,
Interesting point and I don't think that it "hijacks" the thread at all. OTT's willingness to not only fix things, improve things and go the extra mile seems to be in direct contrast to most of the rest of the RV industry.
When I dropped off Twist for some warranty issues back in late August, Tommy told me that they would also be doing some additional work. In asking for more specifics on this he told me that the main battery cables would be replaced (I think he said that they were increasing the gauge of these cables to 4). It seems that in conjunction with the solar equipment manufacturer(s) they had determined that there was a minor voltage drop that could be prevented (reduced) with these new cables.
In thinking about this I was very pleased that OTT would go to this length to "make things" as good as they could be. However, I also thought about what might I be missing if I had not taken Twist in for other work. For my purposes I do not think that these larger cables make much (if any) difference. But, are there other "upgrades" that might mean something to me, even if I have to pay for them? Given that I do not know what I do not know, how am I supposed to know - if you know what I mean? Certainly it would take a fair amount of time and effort for the folks at OTT to "publish" this kind of material/data. I think that this type of thing is one of the greatest benefits of this Forum. It allows for the distribution of information without a great deal of effort being placed on the shoulders of any one party. Of course, the down side is that one has to be somewhat active on the Forum and have enough knowledge to know just what things might apply to their situation. This is not necessarily an easy task either.
For me, the bottom line is that I am more than happy to work with a company that not only produces what I believe to be about the best there is but also does what they can to make sure that the product remains as good as they can make it. As you have said - being familiar with, understanding your camper and its systems, and having a good base knowledge all help in making for a better experience. Having someone at OTT that could "post information" etc. would certainly be very useful and even extend the lead that they already have on being the best.
