Why Proper Height Matters
Safety Issues with Wrong Height
- Too high in front: Less tongue weight, can cause trailer sway
- Too low in front: Excess tongue weight, strains truck rear axle
- Either extreme: Poor braking, headlight aim issues, tire wear
Measuring Tips
- Measure with truck loaded (gear, passengers, tongue weight)
- Trailer should be level or slightly nose-down when connected
- Re-measure if you change truck suspension or tires
