While waiting for our new Escape 19 trailer, which we have named "Blanquillo" for little white thing, I have been researching information on it and similar trailers.  It has several features we haven't had before and a lot of features we have had.  For example, our prior trailer had wheels, tires, bearings, and brakes and I know a lot about how to take care of them, but we didn't have a bathroom or holding tanks, so I need to learn how to, well, dump them.  
And I am discovering a lot I should have known and just didn't pay much attention to.  I have been taking care of the tires and bearings.  Since we had a blowout last fall, I have learned and re-learned about tire care.  I started putting the trailer up on jack stands when it would sit for a while so that the tires wouldn't be stuck in one position with weight on them.  But I haven't adjusted the brakes since we got it.  This is despite the fact that I bought a brake adjusting tool.  I just didn't use it.
And did you know how important it is to check the tightness of the lug nuts after changing a tire?  I didn't but I have seen stories of people losing wheels due to lug nuts loosening.  Or so they claim.  I will check them just to be safe. I haven't had any loosen on me so it obviously doesn't happen often.
There have been two forums that have been helpful to me in learning about the new and the old.  The first one is the Escape forum (http://escapeforum.org) and the second is Fiberglass RV forums (http://www.fiberglassrv.com/forums/)
