I-70 provides the main access to Wentzville, with Exit 208 (Wentzville Parkway) and Exit 212 (Pearce Boulevard) being your best bets for RV-friendly routes. Both exits have wide turning radii and good sight lines. Highway 61 runs north-south through town and connects easily to the interstate without any low bridges or weight restrictions to worry about.
Most roads in the commercial areas along the highway corridor can handle large RVs without problems. However, avoid the older residential streets downtown if you're in a big rig - they're narrow with tight corners. The newer developments on the west side of town have better infrastructure for oversized vehicles.
Overnight parking options are limited to designated RV parks and some truck stops. Walmart doesn't allow overnight parking at their Wentzville location, so plan accordingly. The nearest rest area is about 15 miles west on I-70 if you need a quick break. Winter driving is generally manageable, though ice storms can make things dicey for a day or two.

Explore the Wentzville Area
Hit the dump stations early morning or late afternoon to avoid the busiest periods, especially on weekends when local campers are heading out or returning. Most facilities here have decent rinse hoses, but bringing your own backup hose and nozzle is smart since equipment can break or go missing.
For water fill-ups, several gas stations along Highway 61 have spigots available, though you'll want to ask permission first. The newer truck stops typically have better lighting and wider approaches if you're dumping after dark. Propane is readily available at multiple locations, including some hardware stores that offer competitive pricing.
If you need RV repairs or supplies, there's a decent parts store on Pearce Boulevard that stocks basic maintenance items. The area gets busy during Cardinals baseball season with fans passing through, so expect more competition for dump station access on game days. Keep some cash handy since not all locations accept cards for dump fees.
