Which home sizes fit
Doesn't fit (6 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.
| Item | How it goes in | Headroom | At the door |
|---|---|---|---|
| Won't fit: Won't go through the door opening (3'11" wide × 4'10" high), even tilted. | – | – | |
| Won't fit: Too big for the door opening (3'11" wide × 4'10" high) while kept upright (5'10" tall). It would have to be laid down to get in. | – | – | |

Notes on these numbers
SOURCE CAVEAT: every uhaul.com fetch returned ECONNRESET; all values come from WebSearch results that quote uhaul.com pages (the search tool returns a summarized answer with quoted fragments, not the raw page), so check asWritten punctuation against the live page before publishing. U‑Haul states all rental truck and trailer measurements are approximate. No numeric deck height published (only 'Lowest deck'). Business page disagrees: inside 8' x 4'8" x 5'4", door 4'0" x 4'10". U‑Haul's trailer index also appears to list a '5' x 8' Cargo Trailer w/Ramp' (same interior, ramp capacity 1,000 lbs per one search result) and a tips page says only some 5x8 cargo trailers have a ramp door; not confirmed, so no separate row. Empty weight 900 lbs; max combined weight 2,700 lbs. Cross-check 29 Oct 2026, inside.length: All independents (and U‑Haul's own business page) give the older spec set; only the product-page snippet has ours. Possibly a newer trailer model, unverified. Used the smallest current value (8') instead of 8'1". Cross-check 29 Oct 2026, inside.height: All independents (and U‑Haul's own business page) give the older spec set; only the product-page snippet has ours. Possibly a newer trailer model, unverified. A 4-inch height gap matters for fit. Cross-check 29 Oct 2026, door.width: All independents (and U‑Haul's own business page) give the older spec set; only the product-page snippet has ours. Possibly a newer trailer model, unverified. Wheel wells (29 Oct 2026): U‑Haul trailers carry their wheels outside the box under fenders, so the floor is very likely flat; no text source says so.
Loading tips for this trailer
- Load heavy furniture and appliances first, against the cab wall, and boxes last on top.
