The Towing Lab — Consumer Towing
Calculators, weight science, and technical guidance for trailer, RV, and truck towing. Covers tongue weight, GVWR, payload, hitch selection, and setup physics for Class 1–5 vehicles.
Weight Distribution & GVWR Explained
The four weight checks every tow requires, SAE J2807 compliance, payload-vs-towing-capacity math, and a worked example that shows how a 13,000-lb-rated F-150 can be overloaded on a 10,000-lb trailer.
Read article →The Physics of Tongue Weight: Why 10–15% Is the Golden Rule
Explore the yaw-moment mechanics behind tongue weight, what SAE J2807 really says, and why temperature silently shifts your static readings by up to 8%.
Read article →Why Weight-Distribution Hitches Fail: The Engineering Behind Proper Setup
Spring bar tension tolerances, the 2-degree pitch myth above 2,000 lbs tongue weight, and how a 50-lb imbalance twists your frame over time.
Read article →The 5 Most Common Towing Setup Failures: A Mechanical Analysis
NHTSA data on hitch ball size mismatches, why pin 4 of your 7-pin connector degrades 3× faster than any other pin, and the payload-vs-towing-capacity trap that voids manufacturer liability.
Read article →The Heavy Haul — Commercial Recovery
Semi-truck recovery, heavy-haul permits, air brake systems, and commercial transport operations. Written for Class 6–8 operators, fleet managers, and recovery professionals.
Uprighting a Loaded Semi: The Physics and Protocols of Heavy-Duty Recovery
A fully loaded 53-foot trailer's centre of gravity shifts 8–12 feet during recovery. Understand the controlled-rotation method, multi-point rigging, and why air suspension must be deflated first.
Read article →Air-Line Troubleshooting for Towed Rigs: Diagnosing Semi Brake System Failures
Coupling order, dead rearends, and how a failed air dryer can add 100 feet to your stopping distance. A field-level guide to FMCSA §393.45 compliance.
Read article →Heavy-Haul Permits: The Legal Framework for Oversized Load Transport
The Federal Bridge Formula, superload designation costs ($3,000–$15,000 per route), and the 8 states that operate outside the FHWA unified permit system.
Read article →Securing Exotic Cars vs. Heavy Machinery: Why One-Size-Fits-All Fails
Carbon-fibre crush loads below 200 lbs, the shifting centre of gravity of a raised excavator bucket, and aluminium deck point-load limits that supercar tyres routinely exceed.
Read article →Safety Hub — Checklists, Laws & Protocols
High-utility safety resources covering pre-trip inspection, Move Over law compliance, and roadside protocols — designed for both recreational towers and professional operators.
The Ultimate Towing Safety Checklist
A seven-stage checklist covering weight verification, hitch system inspection, electrical & brakes, tires, cargo securement, driver readiness, and post-departure re-check — for light-duty through commercial setups.
Read article →Move Over Laws: A State-by-State Guide to High-Speed Roadside Safety
All 50 states have Move Over laws, but only 26 specifically include tow trucks. Learn OSHA 29 CFR 1926.600 buffer requirements and the flare placement detail that causes 31% of curve/hill fatalities.
Read article →Field Notes — Gear & Technical Analysis
In-depth equipment evaluation, mechanical analysis, and technical breakdowns of towing and recovery gear — with a focus on what working operators actually need to know.
WLL vs. Breaking Strength: What Winch Manufacturers Don't Tell You
The 3:1 safety factor assumes static loads — not the shock loading of a stuck vehicle extraction. Learn fleet angle losses, wet-rope degradation, and drum layering effects.
Read article →Synthetic vs. Steel Tow Lines: A Mechanical Breakdown for Real-World Recovery
Synthetic UHMWPE rope stores 70% less kinetic energy than steel cable — a life-safety critical difference. Plus: UV-hour tracking, fish-hook fractures, and wet-load ratings.
