Truman Reservoir — officially Harry S Truman Reservoir — is Missouri’s largest lake by surface area at 55,600 acres, created by the U.S. Army Corps of Engineers in 1979 by damming the Osage River in the west-central part of the state. Despite being the largest lake in Missouri by acreage, Truman Reservoir remains significantly less developed and less trafficked than Lake of the Ozarks to the southeast — making it one of the Midwest’s best-kept recreational boating secrets for anglers and families who want expansive water without the holiday weekend crowds. The lake has over 950 miles of shoreline winding through Henry, Benton, Hickory, and St. Clair counties, with vast shallow coves, timbered flats, and an irregular shoreline that creates ideal habitat for largemouth bass, crappie, white bass, walleye, and catfish. The bass and crappie fisheries are the primary draw for serious anglers — Truman consistently produces quality largemouth in the 3 to 5-pound range and crappie fishing on the submerged timber flats is considered among the best in the state.

Trailer Repair FAQ
A professional bearing repack typically costs $200 to $400 per axle. This includes disassembling the hub, cleaning the bearings, inspecting for wear, and “repacking” with high-quality marine-grade grease. If the bearings or races are pitted and require replacement, expect to add $50–$100 per wheel for parts.
It depends on your boat’s weight and which state lines you’re crossing. While many Midwest states (like Illinois and Michigan) require brakes at the 3,000 lbs GVWR mark, others like Ohio and Tennessee have lower thresholds. Because these laws vary significantly across our 16-state corridor and are subject to change in 2026, it is your responsibility to verify the current requirements for every state you plan to travel through.
Even if the tread looks deep, boat trailer tires (ST tires) should be replaced every 5 to 6 years. The combination of sitting in the sun (UV damage) and carrying heavy loads causes “dry rot” in the sidewalls, which leads to blowouts on the highway.
90% of trailer light issues are caused by a bad ground connection. Because boat trailers are submerged in water, the wiring harness and connectors are prone to corrosion. Upgrading to a “sealed” LED wiring harness is the best way to prevent the constant headache of non-functioning lights.
It depends on your boat type and where you launch. Bunk Trailers are best for fiberglass boats and heavy vessels. They offer superior hull support and a simple drive-on loading experience. They are cheaper to maintain but require deeper water to launch. Roller Trailers are ideal for shallow ramps or solo launching. They allow the boat to glide off easily even if the trailer is not fully submerged. However, they have more moving parts to maintain and can cause pressure points on some fiberglass hulls.
