HA! I fixed it! And again I say, HA!
OK, I emailed the warranty folks at RVW. They said to speak to one of their techs, (by name) and he would explain to me exactly what needed to be done. I called and the very nice and helpful guy laid it all out for me.
1.Extend the slide, note which end is too tight.
2.Loosen the bolts on both extention rails where they attach to the slide out on the "outside"
3.Grab a hammer and tap the rails, moving them in the direction of the tight end. Tighten the bolts.
4.Run the slide in and back out again. This should re-center the slide.
The tech said slides do go out of adjustment from time to time. So now that I know what I'm doing, every now and then I'll check to see if the seals are binding and if they are, dig out the 3/4" wrench and the hammer.
That was easy. So what was I all worked up about? See pictures:
