Unfortunately, I have no experience on the end cap replacements, but I can say, just unbolting the bumper covers has caused me issues getting screws to bite again, so I would be really cautious, and I would probably not mess with it. On our Classic though, our end caps are fiberglass, so they seem to be mounted very sturdily.
We made some good progress last night and most of the day today. We got half of the blinds back in, and got a quote on a Levelor blind for the 60" dining window. It came back at $131 with strings, or $181 for strinless. We actually want the string version though, not just for the cost savings, but also to keep the bottom of the blind from wagging around when transporting the trailer. We are checking some online sources as well, so looks like we have it covered.
The most time last night was spent positioning the outrigger, and man can I say what a pain. I spent about 4 hours actually getting it set to the correct height, making sure it was level, etc. Everyone I spoke to, friends, JR Repair, etc., all said, just weld it to the frame in front of the tire. No extra details, and honestly, JR really gave next to no advice on how to calculate where it should be mounted.
It was the easiest thing to say, but actually getting it positioned so that it wasn't too high (causing it to hold the door side of the top to sit off of the front and rear stops) or too low (totally ineffective), was aggravating. So, I actually ended up checking the height of the top at full up, and ended up realizing that I needed to adjust 3 of the 4 cables. Once I did that, then I took a lazer and cast it from the rear where the top touches the rear bumper cover, and set the height of the rubber bumper on the outrigger just about 1/8" above that. It worked out perfectly.
It held the slightly sagging portion of the wall just in front of the door, so that when the top is all the way down, the door closes perfectly and the top sits level. It is clear that HiLo should have built the trailer with these in the first place, at least on the door side.
Here are a bunch of pictures that show the process I went through, and how it ended up:
