Frequently asked questions
Twenty questions people actually search for, answered in a sentence or two with a link to the page that goes deeper.
Prices on this site were last verified October 5, 2026, and if that data ever goes more than 48 hours stale every price on the site disappears rather than ageing quietly. That is the short version of how this place works; the long version is here.
Fitment
- Are truck tool boxes universal?
- No. “Universal” in this market means “fits a range of full-size beds”. Fitment turns on your exterior bed rail width, published as roughly 65 in for an F-150, 64 in for a Silverado 1500, 66 in for a Ram 1500 and 57 in for a Tacoma. Full-size boxes are built around the mid-sixties figures, which is why one does not fit a Tacoma. Shop by truck.
- How do I measure my truck bed for a tool box?
- Measure the exterior bed rail width: outside edge to outside edge, across the top of the rails, at the point nearest the cab, with the tape taut. Then check that figure against the manufacturer's fitment chart. Do not match it to the box's advertised length — the box ends overhang the rails. The full procedure.
- Why is the tool box longer than my bed is wide?
- Because the box's end caps overhang the rails rather than sitting between them, and the mounting requirement is at least 1.5 inches of box resting on each rail. A 69 in box bridging a 65 in rail span is correct.
- Where do I find my truck's bed dimensions?
- We have collated the manufacturers' published figures for all four trucks this site covers, with sources, in the truck bed dimensions chart. Measure your own as well — the published figures describe a bare bed and yours probably has a liner in it.
- Can I put full-size accessories on a Tacoma?
- Some, not most. Anything measured across the bed — crossover tool boxes, bed racks, covers, drawer systems, slides — is sized for full-size beds. Mid-size versions exist for all of them. Tacoma fitment.
Tool boxes
- Which shape of tool box should I buy?
- A crossover if this is your first box on a standard full-size truck — widest product range, best security hardware, least compromise. A side-mount box if you haul flat loads and need the bed floor. A chest if you want no rail space used at all. All five shapes compared.
- Are truck tool boxes waterproof?
- Almost none are in any tested sense and very few publish a rating. Weather-resistant is the honest description. The usual reason a box starts leaking in year three is that a single-skin lid has lost its flatness and no longer meets the seal along its length. Full answer.
- Do I need to drill my truck to fit a tool box?
- Not for a crossover box. J-hook and clamp kits grip the bed rail lip and hold it firmly with no holes, and the box comes off cleanly at resale. Side-mount and underbody boxes almost always need holes. Step-by-step.
- How much weight can a tool box hold?
- Most manufacturers publish a lid load rating at best, and many publish nothing. We print what is published and say so where it is not. In practice your truck's payload is the limit long before the box's structure is. More.
- What is the most secure tool box lock?
- A multi-point gear lock, which drives lock points at both ends of the lid from one key turn. It is the only hardware upgrade that changes the outcome rather than the time taken, because the usual failure is a bar levering a single center latch. Security.
Covers, liners and racks
- Will a tool box fit under a tonneau cover?
- Only a slimline or low-profile cross-bed box, or with a cover specifically notched for a tool box. A standard 14 in crossover box and an ordinary cover do not coexist. Measure from your bed floor to the underside of the closed cover. Clearances.
- Does a tonneau cover improve gas mileage?
- The standard 5-10% claim is contested and we will not print it as fact — independent results have gone both ways depending on speed, tailgate position and cover profile. Buy a cover for weather and privacy. What is actually known.
- Can you put a ladder rack on a tonneau cover?
- Not on the cover — no cover is a structural surface. What works is a rack whose uprights mount to the bed rails outboard of the cover's clamp rail, with the crossbars spanning above the closed cover. Full answer.
- Spray-in or drop-in bed liner?
- Spray-in if the truck's condition will matter at resale, because nothing gets behind a bonded liner to abrade the paint. Drop-in if you want protection that is cheaply replaceable and completely reversible. Full comparison.
- How much weight can a ladder rack hold?
- The common published figures are 800 lb and 1,000 lb, and both describe the rack rather than your installation. Your mounting points, your payload and the raised center of gravity all sit in between. More.
How this site works
- Where do your prices come from?
- Straight from the Amazon catalog, pulled when you load the page, with the date shown. There is no code path on this site that can display a price typed in by hand — the content model has no price field at all. How it works.
- What do “spec-verified” and “owner-report-verified” mean?
- Spec-verified means the assessment comes from manufacturer specifications and fitment data and we have not had that product in a bed. Owner-report-verified means the substantive evidence is the consistent pattern across verified purchaser reports, with failure modes named. Hands-on is reserved for products genuinely handled. The three tiers.
- Do you get paid for your recommendations?
- We earn Amazon commission when you buy through a link, at no extra cost to you. Commission rate is not a ranking input, nobody can pay for a place on a list, and there are pages here that conclude the right answer is to spend nothing. Full disclosure.
- Why do some products show “check price” instead of a price?
- Because we could not verify a current price for that product, so we would rather show nothing than show you an old number. The same thing happens site-wide if our price data goes stale — every price disappears rather than ageing quietly.
- How do I tell you something is wrong?
- Email contact@toolboxandtruck.com with the page and the figure. We will check it against the source, correct it and date the correction. That is a commitment rather than a courtesy — it is set out in our editorial policy.
