Need to run a pair of wires from the front to back of my camper (20 feet)

Where is the best source to buy 2/0 wire?

My local Hardware store either Lowes or Home Depot has THHN cable. A bit stiffer, but available right away. Otherwise its Amazon or Wireandcableyourway.com.

That’s quite the run of wire for a camper. Are you putting this in any kind of conduit or split loom?

I have been buying from here (I am not affiliated) good tinned wire: https://www.pacergroup.net/products/cable/marine-battery-cable/

Electric Wire Cable | Solar Panel Cable | Copper Wire | Electrical Supply Wholesale

If you're looking for immediate shipment of the wire and cable that you need, you've come to the right place with Electric Wire and Cable Specialists.
Have had good experience with this source for about 50ft worth of thick stranded conductor.

It usually comes with some fiberglass residue on the outside of the insulation. So I tend to wipe that off.

I'm adding a 400ah lithium pack and want to have it in the rear storage area instead of up on the tongue of the trailer. I also don't want to do to much hackery to the factory wiring.

The frame has a set of holes through it. It will be loomed and run through grommets
