Replacing plumbing
My 1973 Argosy has copper plumbing. It's a mess of old repairs using rubber hose with clamps, and PVC. Should I repair everything with copper, or pull it all and use polyethylene pipe?

Neither. Take it all out and replace with PEX. A really nice plumbing system for a trailer.

Pex is what I meant by polyethylene.

Pull it out and replace with PEX style tubing and fittings. It's time consuming, but will eliminate your plumbing leaks for a long time to come. I consider it a significant improvement to my old Trade Wind. I'll be sure to boast about it in an ad to sell when that day comes.

A pex conversion on these old trailers is pretty easy.
The work I did on my 75 took a day or two including taking apart and putting together for access.

PEX is what Airstream uses in all their modern trailers. Much lighter and more forgiving than copper.

There seems to be a difference in the pex pipe and fittings used in RVs and that used in houses.The household stuff sold at Home Depot is a lot cheaper. Any reason not to use it?

No reason at all.
I replaced ALL of the copper in my ARGOSY with PEX. 23,000 miles; 5 years and ZERO problems. Bought it a Menards.

PEX is definitely the way to go. We did it 5 years ago and have had absolutely no problems.
Caution: Draw a complete diagram of the old system before you tear out the copper.

X2 for making a diagram. A must for me whether it's plumbing or electrical.
