If boiled down to one word, that word would have to be corrosion. Or maybe oxidation (yeah, I know, that's just another variant of corrosion). Since your rig spends half the year in the wet, corrosive atmosphere of New England...where acid rain and salt air are common...and you make those twice annual treks across the continent (bet a lot of those miles have been in pretty wet conditions)...there has got to have been at least some gradual corrosion/oxidation in all those junctions that both TM and Ford engineered into your trailer/TV.

One of the things I have going for me is the relatively dry climate of Colorado (to us, a horribly muggy summer day is whenever the relative humidity exceeds 15% ). Furthermore, I try really hard to only tow on dry roads...which isn't as hard as it sounds since about 90% of our summer rainstorms occur in the afternoon. And we have almost no atmospheric pollution...in particular almost none of those nasty sulphur oxides. Stuff hardly even rusts here and electrical contact problems are exceedingly rare.
