Tier One RV LLC

Tier One RV LLC is a mobile RV tech based in Pasco, Washington. It comes to you, wherever the rig sits, rather than asking you to bring it to a shop.

It handles RV inspections, general repair, warranty repair and winterizing. Its pages do not list which specific systems or RV types it covers, so ask when you call whether it can handle your make and your particular problem, whether that is a fridge, a slide-out or something else.

No hourly rate, trip fee or diagnostic fee is published, so ask about the trip fee before you book. No service area radius is stated either, so confirm it reaches your town or campground before you commit. For after-hours contact, it offers a separate line, described as available "for immediate support," which is handy if something breaks at night, though a live callback will likely wait for business hours.

It backs its work with a 90 day labor warranty, which matters because a repair that fails a month down the road should not cost you twice. It is veteran owned and operated, and Tony is the tech named on the listing. Google rates it 4.8 stars from 65 reviews.

This is a good fit for an owner in or around Pasco who wants inspection or repair work done on-site and is comfortable calling first to confirm pricing, service area and exactly what systems the tech can take on.
