Which home sizes fit
Doesn't fit (5 home sizes)
Each home size is a typical furniture list plus the box counts from a moving guide. Our packing fills about 70–80% of a truck; a careful pro load fits more.
Will big items fit?
Tightest fits first. Headroom is the space left above it as loaded; at the door is the clearance getting it in.

Notes on these numbers
Page disclaimer: "These capacities, dimensions and mileage are approximations and may vary by manufacturer." Penske compare table (https://www.pensketruckrental.com/trucks-and-vans/) footnote: specs "based on Penske's most commonly rented fleet" and vary by make, model, and year. Door opening, deck height and over-cab are not listed on Penske consumer pages or the compare table; WebSearch (standard) found no brand source for them. 'up to' appears only once, before the length; width/height are written without it. Outside values are NOT on the 12' page; they come from the comparison table on the cargo-van page (column '12 Foot Truck'). CAUTION: that table's 'Width' of 6'7" is only 1 in. more than the stated interior width (6'6"), which looks implausible for an exterior width - treat with suspicion. Rear roll-up door, no ramp, not towing compatible, no flat floor per compare table. '1-2 rooms', '78 sq. ft.' Outside sizes are left out on purpose: the source gives a clearance height or numbers from another page, not the box size. Wheel wells (29 Oct 2026): Penske's compare table does not mark the 12' as flat-floor (the 16', 22' and 26' are), so it likely has wells. No source gives their size; not modelled.
Loading tips for this truck
- Load heavy furniture and appliances first, against the cab wall, and boxes last on top.
