01 What makes it unique
Bigfoot lists the 2500 Series 25B17.5FB at 3,360 lb dry, a GVWR of 4,300 lb and a tongue weight of 315 lb. Bigfoot prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 17'-5" long and 8'-8" high. Bigfoot prints its tanks as 30 gal fresh, 21 gal grey, 21 gal black.
Among the 7 2500 Series floorplans Bigfoot’s 2500 Series model pages on bigfootrv.com (no model year stated) lists with a published dry weight, it is number 1 from the lightest, in a range from 3,360 lb (2500 Series 25B17.5FB) to 5,563 lb (2500 Series 25B25FB). Every figure in that comparison is Bigfoot’s, read from the same set of model pages.
Every number on this page was read on 6 Nov 2026 from Bigfoot’s own 2500 Series model pages on bigfootrv.com (no model year stated) for the 2500 Series 25B17.5FB, which names no model year; the figures are shown as the maker published them, and no year is claimed for them.

How these published figures sit against the rest of the catalogue: travel trailer tongue weight by size; fresh, grey and black tank sizes; camper trailer size chart.
Federal tire recalls naming this size. NHTSA’s recall file names ST225/75R15 in 2 tire recalls: 14T015000 (Dynamic Tire Corp., 2014; make TOWMAX STR; model ST); 17T014000 (Triangle Tire USA, 2017; make TRIANGLE; model TR643). A tire recall covers only the brands, lines and DOT date codes it lists, and this page does not know which brand of tire this trailer was built with, so read the brand and DOT code on your own sidewalls before relying on this list. Only 242 of NHTSA’s 788 tire recalls name a size in their summary, so a size with no match is not a clean record (NHTSA recall file, read 12 Oct 2026).

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 (4,300 lb) and the upper loaded tongue estimate (645 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433).

04 Notes on this floorplan
What Bigfoot does not publish for the 2500 Series 25B17.5FB
Bigfoot prints no cargo carrying capacity, 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
4,308 lb dry and 7,500 lb GVWR, against this model’s 3,360 lb and 4,300 lb.
