01 What makes it unique
Brinkley lists the 2027 Model R 3710 at 18,750 lb dry, a GVWR of 23,500 lb and a pin weight of 3,450 lb. Brinkley prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 41' 4" long and 13' 4" high. Brinkley prints its tanks as 100 gal fresh, 104 gal grey, 52 gal black.
Every number on this page was read on 8 Nov 2026 from Brinkley’s 2027 Model R floorplan flyer (listed under model year 2027 in Brinkley’s own document library; the flyer prints no year), which Brinkley’s own document library files under model year 2027.

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 (23,500 lb) and the upper loaded pin estimate (5,875 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).

04 Notes on this floorplan
What Brinkley does not publish for the Model R 3710
Brinkley prints no cargo carrying capacity, interior height and 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
The weight label every RV trailer carries by law (49 CFR 571.110 and 571.120) governs the towing decision, not this page.
