Public scales in Fillmore / Nephi (I-15)
Two CAT Scales verified on the operators’ own location pages along I-15 through mid-Utah, south to north: Love’s #835 Fillmore (Exit 163) and Flying J #743 Nephi (Exit 222). Useful for U-Haul and PPM moves between southwestern Utah and the Salt Lake valley, RVs headed for Fish Lake / Capitol Reef approaches, and horse trailers on I-15. Heading southwest, the previous verified cluster is on St. George / Cedar City / I-15 (Parowan Exit 78). Flying J Beaver #509, TA Fillmore #0519, Flying J Scipio #510, ONE9 Fillmore #1479, Flying J Richfield #773, and TA Express Salina still omit CAT from their own amenities lists — held back.
Filters hide cards, not industrial rows. CAT will not weigh under 2,000 lb — use a dedicated house for cars and empty utility trailers.
No verified dedicated public scale house between Parowan and Nephi
Utah does not publish a CDFA-style public-scale grid we can cite for this corridor, and ScaleRegistry’s public-weighing page lists no walk-up house in Millard or Juab County UT. We are not inventing one from industrial scale vendors, recyclers, landfill gate scales, or third-party trucker directories. Every stop below is a CAT Scale at a truck stop, verified on the operator’s own page.
CAT Scales on I-15 through Fillmore and Nephi
We list only stops verified on the operator’s own location page. Love’s #835 lists CAT Scales among amenities; Flying J #743 lists CAT Scale in its own amenities and answers yes to “has a CAT scale”. 2,000 lb floor. No corner weights. Weigh the whole rig, then drop the trailer and weigh the tow vehicle for the trailer number. Do not unload horses at a truck stop. Utah weighmaster rules differ from California — confirm ticket needs with your TO or DMV equivalent. Use CAT’s locator for other stops.
Love’s own #835 page lists the store as Open 24-hours and CAT Scales among amenities. That is the store’s hours, not a published CAT-staffing schedule. Confirm the scale is working before a middle-of-the-night trip.

Handy for mid-Utah U-Haul and RV weigh-ins between St. George / Cedar City and the Salt Lake valley. CAT 2,000 lb floor; no corner weights.

Flying J’s own Nephi page (I-15 Exit 222) lists CAT Scale among amenities and answers yes to “Does this location have a CAT scale?”. Juab County UT; about 60 miles northeast of Fillmore on I-15 — north end of this corridor before the Provo / Salt Lake basin. Useful for PPM / U-Haul and RV weigh-ins headed toward I-15 / US-6. CAT 2,000 lb floor; no corner weights. Utah weighmaster rules differ from California — confirm ticket needs with your TO or DMV equivalent. Do not unload horses in the lot. Confirm on CAT’s locator. Not a DOT station.
Highway weigh / commercial-enforcement sites on I-15 are for commercial vehicles — not a place to buy a civilian weighmaster ticket for a U-Haul, RV, boat, horse trailer, or PPM load. Follow posted signs; do not treat this directory as a bypass guide.
What we still need to verify
Any dedicated public scale house in Fillmore, Nephi or Millard/Juab County with an operator page that sells walk-up weighmaster certificates. Flying J Dealer #509 Beaver (I-15 Exit 112), TA Fillmore #0519 (same Exit 163 cluster as Love’s), Flying J Dealer #510 Scipio, ONE9 #1479 Fillmore, Flying J #773 Richfield, and TA Express Salina still omit CAT Scale from their visible amenities lists — held back. Livestock policy everywhere. Store-listed 24h vs published CAT staffing.
