The converter dolly tongue is:
Correct answer: B. Heavy and may require a tongue jack or two-person handling
Why: Tongues are heavy steel and can crush feet or strain backs. Use jacks, dollies, and proper lifting technique.
Each additional articulation point multiplies rearward amplification. A driver pulling triples must steer earlier, brake sooner, and inspect twice as much equipment as a single-trailer driver.
Learn the correct trailer placement order by weight, the procedure for converting a single to a double, and the special inspection items unique to converter dollies and pintle hook assemblies.
