01 What makes it unique
Highland Ridge lists the 2019 Silverstar THX SF350H at 12,500 lb dry, a GVWR of 16,905 lb, a net carrying capacity of 4,405 lb and a pin weight of 2,905 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
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 3 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.
How the SF350H differs from the other two Silverstar THX floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 12,500 lb: heaviest of three; next is the SF383H (12,425 lb).
- Cargo capacity, 4,405 lb: smallest of three; next is the SF383H (5,525 lb).
- GVWR, 16,905 lb: second-lowest of three, between the SF327G (16,850 lb) and the SF383H (18,000 lb).
- Pin weight as a share of dry weight, 23.2%: second-smallest of three, between the SF327G (22.5%) and the SF383H (23.4%).
Next to the SF383H, the nearest lighter floorplan by dry weight, the SF350H is 75 lb heavier by dry weight, has a GVWR 1,095 lb lower and has 1,120 lb less cargo capacity; the two publish the same pin weight, exterior height, interior height, fresh tank, grey tank and black tank.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (16,905 lb) and the upper loaded pin estimate (4,226 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published figure, because loaded is never lighter than that.

04 Notes on this floorplan
What Highland Ridge does not publish for the Silverstar THX SF350H
Highland Ridge prints no 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.
05 How it compares
12,425 lb dry and 18,000 lb GVWR, against this model’s 12,500 lb and 16,905 lb.
06 Loading it for a trip
A full 110-gallon fresh tank is about 913 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 21% of the Silverstar THX SF350H’s 4,405 lb cargo capacity, leaving 3,492 lb. Across 3 Silverstar THX floorplans the water share runs 16% to 21%, and this plan’s is the highest. Nearest on that share: Silverstar THX SF383H at 17%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
