I get part numbers from the various manufacturers websites, then do Google searches for them. I have gotten a lot of stuff from Tweety's RV, RV Upgrades and Amazon. The local Camping World doesn't do well with stocking or special orders. I do special orders from a semi-local Airstream/FR dealer about an hour from me. I can call them with the numbers, they give me the price and order it. I pick it up the next time I come through.
