2019 Highland RidgeSilverstar THX SF383H

Highland Ridge lists the 2019 Silverstar THX SF383H at 12,425 lb dry, a GVWR of 18,000 lb, a net carrying capacity of 5,525 lb and a pin weight of 2,905 lb. Highland Ridge’s own figures do not add up — a conflict, stated not resolved: 12,425 lb dry plus 5,525 lb carrying capacity is 17,950 lb, against a printed GVWR of 18,000 lb. All three are shown as Highland Ridge prints them and none is corrected; the federal label on the trailer is the one to trust.

It is 157" high. Highland Ridge prints its tanks as 110 gal fresh, 114 gal grey, 82 gal black.

Among the 3 Silverstar THX floorplans Highland Ridge’s Silverstar THX brochure (listed under 2019 in Highland Ridge’s own brochure library; the brochure prints no year) lists with a published dry weight, it is number 2 from the lightest, in a range from 11,250 lb (Silverstar THX SF327G) to 12,500 lb (Silverstar THX SF350H). Every figure in that comparison is Highland Ridge’s, for the same model year.

Every number on this page was read on 6 Nov 2026 from Highland Ridge’s Silverstar THX brochure (listed under 2019 in Highland Ridge’s own brochure library; the brochure prints no year); model year 2019 comes from where the maker files it on its own site, not from the document’s text.
