Well, we made it back with our "new" 1968 Tradewind. All went pretty smooth, except the grease seal fiasco and the tail lights.
Anyone else with a similar year have old national 292100s? - No one in our area or Santa cruz could get us a seal to fit. I'm wondering why others haven't had this problem. Is it a 68 or a tradewind issue? From what I gathered it is a certain measurement ( outter dimension) that makes it an odd-ball size. I couldn't believe no one could get their hands on seals that would fit. I even had a bearings place, with all the specs, calling around for me- nothing. Inland got them to me overnight, so it all worked out - but of course $$$$ shipping.
Brakes: turned out the brakes were wired to the TVs brake lights ... so the trailer brakes would only lock up. They switched wires and the brakes functioned great. But down the road the tail lights didn't come on. The RV place had them working, when connected to their tester deal. Did the wire get in the wrong place when they rewired the plug? Anyone know what color wire the tail lights are? The trailer tow wire is not original, so the 68 schematic doesn't help. [TV Silverado 2004- color wire for this too?]
All in all the trip was great. Traffic and narrow San Fran streets were no problem. The wardrobe mirror broke - we're NOT superstitious -

and the oven door comes loose? I need seriously new cabinet door latches. No broken windows on the trip ... yipee!! We did get a rock thrown at our TV though, which made a nice pit

!!
The carwash made her gleam! Now I can't wait to clean and find out just what the first step will be. Hopefully I'll get some pics here soon!!
