What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Thule Motion 3 XL
One whitelisted hands-on source (GearJunkie, Nov 2025) tested the 18-cu-ft Thule Motion 3 XL, rating it 8.3/10 and naming it Best High-Capacity box: it reads as lightweight for its size, is aerodynamic with a clean, sporty look, installs by one person despite the bulk, and has a solid build; the main knock is price (Value scored 7/10, the lowest of its four category scores). No per-box efficiency (mpg) or noise (dB) figure was printed for the XL, so measured is empty. (1 sourced review, 1 lab-tested.)
Praised: Aerodynamic profile with a clean, sporty look; Easy one-handed access with a ground-level strap to pull the lid shut, reachable even on tall SUVs; Fast one-person install and removal despite the size.
Flagged: Expensive; weakest scoring category was Value (7/10); Not the lightest model tested, at a 51-lb spec weight for the XL.
