Welcome to the forum, and congrats on your "new" camper! There is a bunch of information in this forum about HiLos and you should spend a good deal of time looking through it. In particular, the videos found in Post #3 in this thread:
https://www.hilotrailerforum.com/f49...-youtube-1233/ are well worth your time. Don't be put off by the first one, which just seems like an ad of HiLos, the rest are very valuable.
I have the same trailer, although it's a bit newer. Still, HiLo made very few changes through the years, so I suspect I can give you some worthwhile advice on yours.
