there has got to be some type of plastic that is more uv stable, a friend told me of a black pipe that grainger sells but on their website they sell tons of black plastic pipe, just not sure what to use but don't think i'll use copper wouldn't the vibrations tear apart the joints???

Most all of the RVs and tailers these days us a PEX type pipe/hose for the water system. the grey and black water tanks use black PVC type pipe. The Black pipe is UV resistant and will not let the sunlight in to assist in the growth of bacteria and will cause issues and smells. Copper could be a bit expensive depending on how much line you have to run but since it is all part of the trailer, if you sweat weld it correctly you shouldnt have any issues with joints pulling apart.

ok so it looks like you have got me convinced to use soft copper, i didn't know you could sweat them i thought it was only compression fittings? right? or am i thinking funny?
I only need to run a foot or two inside past the bulkhead of the trailer so will be copper the whole way.

Solder desn't work well when the pipe is subjected to vibration
Working "well" is relative. I've worked with many production machines with soldered copper joints. They operated and vibrated 24/7/365 for many years. More vibration than a horse trailer's life. The key is to support the piping to the frame yet allow differential expansion.
OP: Do drain the system for the winter or freeze protect the pipe. Plastic or copper will burst when filled with freezing water.

Not to ask a silly question- but where exactly will your plumbing be exposed to the sun? I don't think I've seen a LQ or travel trailer where this is an issue? If it is all inside- I'd vote for the pex option. Now LP gas plumbing is a different story, but I assume we are talking potable water in this case.
