Truck Rentals in Colorado — Pickup, Box, Flatbed (Denver · Colorado Springs · Aspen)
Colorado is the highest US state by average elevation (6,800 ft) — Rocky Mountain alpine routes require diesel HD trucks losing minimal power (gasoline engines lose 3%/1,000 ft). PickRV's CO truck catalogue spans F-Series + Silverado + Ram pickups (gas + diesel), box trucks for moving, and overland-prep Tacoma/4Runner for Rocky Mountain NP + alpine trailheads.

What the Colorado DMV doesn't tell you
Context the official .gov pages skip — sourced facts, not brochure copy.
Colorado altitude impact: gasoline engines lose 3% power per 1,000 ft (Aspen 8,000 ft = 24% power loss). Diesel engines (Cummins, PowerStroke, Duramax) lose much less — PickRV recommends diesel for sustained mountain travel.
Trail Ridge Road (RMNP) is the highest paved continuous road in any US national park (peaks at 12,183 ft) — closed Nov-May. Stock pickup OK in season.
CDOT's chain laws on I-70 (Vail Pass, Eisenhower-Johnson Tunnel) are the most-enforced US chain laws — rentals usually include chain set or AWD/4WD certification.
Independence Pass (CO-82, Aspen to Twin Lakes — 12,095 ft) is the shortest summer Aspen-Denver alternative; closed Nov-May.
Denver Airport rental return shuttle 15-20 min; budget time. DEN is one of largest US airport rental complexes.
CO coverage is concentrated in Denver + Aspen + Vail. Colorado Springs + Estes Park smaller.
Straight answers
Colorado truck rental FAQ
Do I need a diesel pickup for alpine Colorado driving?
Not required but recommended for sustained alpine travel (Aspen, Vail, RMNP). Gas engines lose 3% power per 1,000 ft of elevation. Diesel engines lose far less.
Are CDOT chains mandatory for rental trucks?
Yes when chain law in effect (typically I-70 mountain passes Sept-May). Most rentals include chain set or AWD/4WD certification (4WD exempts in most cases).
