REC TEC Stampede (RT-590) owner's manual: 592 sq in cooking area (767 with the optional second shelf), 30 lb hopper, 200 F to 500 F in 5 degree steps plus LO and FUL settings: https://5004282.app.netsuite.com/c.5004282/SSP%20Applications/NetSuite%20Inc.%20-%20SCS/SuiteCommerce%20Standard/manuals/Stampede(RT-590)manual.pdf. Discontinued as RT-590.
Calculator burn assumption
0.70 lb/hr at 225 F. Planning number only. Not a lab test.

Hopper hours and pellets per cook

A full 30 lb hopper covers an overnight 12 lb brisket at 225 F even in winter: about 16 hr 30 min of cooking with about 5.4 lb to spare. At 275 F in winter the full-hopper clock drops to about 15 hr 51 min.

How long a full 30 lb hopper runs on the Recteq RT-590 Stampede, after the 0.35 lb startup pad. Burn starts at the 0.70 lb/hr assumption at 225 F and scales with set point and weather, the same math as the calculator.
Set pointMild (about 60 to 80 F)Winter / sub-freezing
225 F42 hr 21 min at 0.70 lb/hr20 hr 10 min at 1.47 lb/hr
250 F37 hr 20 min at 0.79 lb/hr17 hr 46 min at 1.67 lb/hr
275 F33 hr 18 min at 0.89 lb/hr15 hr 51 min at 1.87 lb/hr

Same 30 lb hopper elsewhere in our database: the Pit Boss Austin XL (about 25 hr 47 min), the Pit Boss Navigator 850 (about 29 hr 39 min), and the Recteq Deck Boss 590 (about 42 hr 21 min), counting a full hopper at 225 F in mild weather on each grill's own assumed burn rate.

Pounds of pellets for two common cooks on the Recteq RT-590 Stampede, startup pad included. Cook time is the calculator's planning estimate for the meat and set point.
CookPlanned timeMild (about 60 to 80 F)Winter / sub-freezing
12 lb brisket at 225 F16 hr 30 min11.9 lb24.6 lb
8 lb pork butt at 250 F10 hr 42 min8.8 lb18.2 lb

Those pounds include the startup pad and assume a full hopper at the start. For how meat, set point, and bag size change the total, see how many pounds of pellets a smoke really takes.

Each pellet figure opens that cook in the calculator with the Recteq RT-590 Stampede already picked, or run the winter brisket for this grill in the calculator and change the weight, temp, or weather yourself. Wind, wet pellets, and a leaky lid are not in the math, and they usually burn more.

Notes

Legacy model, still the one people compare. Later renamed in the Deck Boss line. Heavy lid, big hopper for the size.

PelletDeck did not run this grill in a lab. The burn assumption exists so the calculator has a starting point. Override hopper size if your unit differs.
