Why we publish

Most RV owners get blindsided by repair quotes because nobody tells them what the work actually costs. Dealers don't.

Forums are crowded with armchair experts who have never held the part in their hands. We publish what we charge, what the parts cost wholesale, what the parts cost retail at Camping World, and what an honest mobile tech bills - so when you call us or anybody else, you can tell whether you're being quoted fairly.

The catalog grows weekly. Every article is field-tested before it goes live - meaning we wrote it after fixing the problem on a customer's rig that week. No theory, no AI hallucinations, no copy-paste from the manufacturer manual.
