Comparison

U-Haul 20' vs Penske 22'

These trucks are often shortlisted for 2–3 bedroom moves, but Penske’s extra length comes with much higher listed payload—not a minor spec tweak.

Short answer

U-Haul 20' lists 1,016 cu ft and 5,700 lb payload; Penske 22' lists 1,200 cu ft and 10,000 lb payload. Pick U-Haul when published rear doors and a slightly shorter wheelbase matter and weight is modest. Pick Penske 22' when you need both more volume and substantially higher weight headroom—especially for garage and workshop contents.

Choose by scenario

Standard furnished 2-bedroom

Volume on both trucks may suffice with disciplined packing. If the inventory includes dense storage, Penske’s payload advantage shows up before the cubic-foot difference does.

Third bedroom or home office

The extra ~184 cu ft on Penske can absorb desks, bookcases, and guest-room furniture that make a 20-foot box feel aisle-starved.

Cross-brand one-way

Route and location availability may decide before specs do. Model both trucks with the same inventory so you are not comparing marketing names at the counter.

Two different “almost 22 foot” stories

Marketing length puts these trucks in the same conversation, but listed volume differs by nearly 200 cu ft and payload by more than 4,000 lb favoring Penske.

Treat this as a heavy-duty vs moderate-duty choice as much as a space choice—especially if you already know the move includes appliances.

Driving length vs capacity

Two extra feet of box on Penske change alley turns and campground-style parking less than a jump to 26 feet, but more than staying on U-Haul’s 20'.

If drivers are nervous in large vehicles, weigh whether a lighter 20-foot U-Haul plus a second trip beats one long Penske load.

Door data asymmetry

U-Haul’s published rear-door width and height help pre-check sofas and mattress sets. Penske requires a phone call or on-site measure for the same confidence.

When the bottleneck piece is known, door data can pick the brand before cubic feet enter the chat.

Related sizes on each brand

U-Haul shoppers who do not need Penske-level payload might still fit a 15' with higher weight rating, or size up to U-Haul’s 26' for volume—see those compare pages instead of defaulting to 20'.

Penske shoppers between 16' and 22' should read the 16 vs 22 page; U-Haul-only shoppers should read 20 vs 26 before booking.

Decision framework for 20' U-Haul vs 22' Penske

Published anchors: U-Haul 20-foot at 1,016 cu ft / 5,700 lb payload; Penske 22-foot at 1,200 cu ft / 10,000 lb. Penske leads on both volume and weight; U-Haul leads on published rear-door data and a slightly shorter wheelbase.

Choose U-Haul when the inventory is moderate on weight, you want known door openings for a sofa or mattress check, and the shorter box eases apartment loops or alley parking.

Choose Penske 22-foot when garage gear, appliances, and boxed storage push toward the 5,700 lb ceiling, or when the third bedroom and office furniture need the extra ~184 cu ft of floor.

Remember U-Haul’s own quirk: its 15-foot lists 6,385 lb—higher than the 20-foot. If weight is the worry and volume still fits a 15-foot, that U-Haul option can beat both trucks in this comparison for dense loads.
