Well, the LED tail-lights are in, and work well; the trailer has been de-siliconized; all four windows
have been removed, butyl-taped, and installed into new interior wood frames, with stainless screws - no more leaks
; but the most (best?) difference for the work/price was replacing the fibreglass in the front window cover. It was eroded to the point that the fibres were blowing in the wind, the glass was yellowed, and the dirt would not come out. Until I had the new ones in, I did not realize just how far gone the old ones were. Absolutely no more trailer reno's till next year. It's like eating one peanut - it's hard to stop.
