Short, opinionated list of RV parts, tools, and supplies our techs reach for every week. We do not link to anything we have not installed, broken, or replaced on a customer's rig. Affiliate links - your price does not change.
The white tube of Dicor 501LSW is what we run through on every roof reseal. Self-leveling, UV-stable, bonds to EPDM and TPO and metal. Buy it by the case if you maintain your own roof.

The number-one part we swap on a Level-Up auto-level fault. The original sensor's MEMS chip drifts after 5+ years in the sun. Genuine Lippert OEM, not the knockoff.

Direct replacement fabric for Carefree slide toppers. Comes in standard sizes that fit 90 percent of fifth wheels and travel trailers. We replace these once the original delaminates.
View on AmazonThree rules. First, the part has to be on a customer's rig today, not a spec sheet. Second, the brand has to honor warranty without making the customer fight for it. Third, the part has to be cheaper or more durable than the dealer alternative - both ideally.
We do not run sponsored placements. The links above are commission-affiliate links - if you buy through them the retailer pays us a small fee at no extra cost to you. The list is short on purpose. There are 200 brands of RV water pumps on Amazon. We use one. That is the one we link.
RV cleaners, polishes, and most "RV-specific" cosmetic products. Most of them are repackaged retail chemicals at 3x the price. Use Dawn for grease, ammonia-free Windex for the windows, automotive paste wax for the gel coat. You do not need an "RV" label.
Off-brand replacement converters. Progressive Dynamics, WFCO, Magnum - all good. Anything else and you are gambling.
Tank treatments. The expensive enzymatic ones do the same job as a cup of dish soap and a gallon of water dumped down the toilet. Save the $40 a bottle.
