Built for owners of the Tune M1, a lightweight pop-up truck camper for half-ton and mid-size trucks. Search community-verified gear weights, calculate real payload capacity, and share your rig before you ever load the truck.
The Tune M1 is a lightweight pop-up truck camper from Tune Outdoor. The mid-size M1 weighs about 400 lbs dry with a 72" interior width; the full-size M1 is wider at 78"; the smaller M1L starts at 322 lbs with a 60" interior width. All three mount in the bed of a half-ton or mid-size pickup and pop up to give 6'4"+ of standing room. The M1 ships with 440+ feet of T-track for modular interior buildouts, three full-opening aluminum awning doors, six canopy windows, and a 3-year limited warranty covering defects in materials, workmanship, and structural integrity from the date of installation, plus lifetime customer support. Base prices run $12,999 (mid) and $13,999 (full).
The M1 interior buildout guide walks through DECKED floors, 80/20 framing, cabinet plans, kitchen units, and the order owners tackle them. It's the most-discussed M1 topic in one place.
Most slide-in truck campers run 1,500–3,500 lbs dry, which rules out every half-ton and mid-size pickup before the conversation even starts. The Tune M1 sits in a much smaller bracket of pop-up campers built around weight discipline. The dry-weight table below shows where the M1 lands.

This tool exists because the M1 community needed it. It's free to use, no sign-up required. Just a tool, built by someone deep in the research, for people doing the same. Not affiliated with Tune Outdoor. Not a marketing site. Not a place that pushes you toward whatever pays the highest commission.
From ordering to first night out: guides, gear picks, and community knowledge all in one place.
These are factory-rated maximums. Your actual door sticker will vary by trim, options, and accessories. Always verify before loading.

This tool is free to use. But hosting, domains, and the occasional cold brew cost something. If this saved you from a blown suspension or an overloaded rig, consider tossing a few bucks toward the next cup. Zero pressure.
