Having trouble choosing a trailer brand/build material

Hey folks. I’m in the planning stages of a conversion and I’m stuck on what brand to get, and even struggling to decide between steel and aluminum. If it helps, this is what I’m looking to do.
A 7x14 flat nose ideally with one HD axle that sits a little higher. I plan to pull this with an older Tundra (5.7L 4x4) and will mostly be on BLM roads, remote boondocking, etc. I’m copying the layout of the trailer in this video ( https://youtu.be/lWwgzO5_Xx8?si=7sGlRfq3nCrwz_7Z ) with a few adjustments. The things I would like to come with the trailer are, AC, shower power plug, basic electrical package and I’d like a quality build construction wise. I don’t need a Cadillac of trailers but I don’t want junk as I plan to use this for many years and Into retirement. A Hail Mary of my wish list is a manufacturer that offer a Happijac bed lift system but I don’t think I’m gonna find that.
I don’t mind driving but I’m in the western midwest so I’d rather not go to CA or FL for a trailer. I did a search for brands but after 3 pages I wasn’t getting much back so figured I’d post. Thanks in advance for any assistance you can provide.
