With three paid options to choose from, you'll have flexibility in timing your waste disposal needs around your travel schedule.

Pomona sits at a major highway junction where Interstate 10 meets State Routes 57 and 71, providing excellent motorhome access from multiple directions. I-10 runs east-west through the heart of the city, connecting to downtown LA about 30 miles west and the desert regions to the east. SR-57 heads north toward the San Gabriel Mountains and south to Orange County, while SR-71 provides a direct route to the Inland Empire.
RV routing through Pomona is generally straightforward, with most major streets capable of handling larger rigs. However, avoid the narrow residential streets north of Foothill Boulevard, especially if you're pulling a long trailer. The Garey Avenue corridor offers the best north-south access for RVs, with wider lanes and fewer restrictions than some of the older downtown streets.
Overnight parking options are limited in the immediate area. The nearest Walmart that typically allows overnight motorhome parking is in West Covina, about 8 miles northwest. Several truck stops along I-10 provide overnight parking, though you'll need to check current policies. During fair season (typically September), the Fairplex area gets congested, so plan extra time for maneuvering around the dump stations.
Winter weather rarely affects travel here, but summer heat can make dumping less pleasant during midday hours. The area's elevation of about 900 feet means temperatures are slightly cooler than the desert regions to the east.

Explore the Pomona Area
Hit the dump stations early morning or late afternoon during summer months to avoid the heat and crowds. The facilities near the fairgrounds get busiest on weekends and during event seasons, so weekday visits often mean shorter waits and easier maneuvering. Most stations here don't provide rinse water, so bring your own tank flush if you prefer a thorough cleaning.
Fuel up at the Pilot Travel Center on Indian Hill Boulevard if you need diesel – it's one of the few truck stops in the area with easy motorhome access and competitive prices. For propane, several U-Haul locations in town offer tank exchanges, with the one on Holt Avenue being particularly motorhome-friendly with good clearance and pull-through access.
Water fill-ups can be challenging in Pomona since most stations focus strictly on waste disposal. The Fairplex facility sometimes allows water fills, but call ahead to confirm. Otherwise, plan to fill up at a full-service Camping or travel center outside the immediate area.
If you need motorhome repairs or supplies, Camping World in nearby Colton (about 20 miles east) offers comprehensive services. For basic supplies and groceries, the shopping centers along Foothill Boulevard provide good motorhome parking and easy access to major retailers. The area around Cal Poly Pomona has several gas stations with large parking areas suitable for RVs.
