04 Notes on this floorplan
What East to West does not publish for the Tandara 389DS
East to West prints no GVWR, tire size, interior height, sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.

11 NHTSA safety record
NHTSA holds 3 recall campaigns and 6 owner complaints (model years 2005 on) against the Tandara line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 6 complaints have been filed on this line — not enough to say what fails most often. They cover structure, tires and electrical system.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Tandara line page.
