Regardless of the drive wheels the engine needs to be on the dolly. ie rear wheel drive vehicle would still get loaded with the weight of engine on the dolly otherwise your spring loading the secondary pivot point. The rig will not can but will sway uncontrollably & for most causes jackknifing to the point of crashing.
Nice project. I prefer your swivel design VS depending on the steering wheel turning on the towed vehicle. How/why did you decide to limit pivot action to 15deg? Was there any tendency for the dolly or towed car to swerve/'wiggle' at hwy speeds? Or with passing big trucks? BTW, I've built lots of spring-less ultra low-deck small flat trailers. Rough riders when empty so I reduce tire pressure to 15PSI when lightly loaded. I've towed them with low PSI tires from Mich to the east coast, and out west. No noticeable incr tire wear, I do check low PSI tires for heat build-up.Thanks/T
The 15 degree swivel was the most I could pivot without the towed vehicle contacting the fenders. The vehicle wiggle is eliminated by locking the steering wheel and having the wheel straps very tight. BTW - Car dollies need to pivot to work properly. Non pivoting dollies drag their wheels sideways around corners and unlocking the steering wheel does not prevent this. Thanks for the comment - D
The plates that the tires are on are sitting on are on two pieces of 3/8" plywood that are secured to the main trailer. The plates slide on the plywood. At the pivot point, I stacked washers so that some of the weight of the cradle was supported in the middle of the trailer. Did you watch all four parts of the video? I think it's part 3 that shows the part in question. I plan to replace the plywood with 1/2" plastic. Thanks for watching. D
@@deegee8032 thanks yes watched all 4 ....so the blue painted plywood are the sliders.....yes i was trying to think of something thick and slippery and cheap, wonder if a kitchen cutting board would work?....thanks for the video....Brett
A cutting board was my first thought but the only ones I could get locally were $30 each and I needed to use the trailer that week and I didn't have time to find a cheaper one online. The plywood worked fine for the 800 mile trip. I used lacquer spray paint and made sure both surfaces were very smooth. D
Clever design.
Thank you so much for sharing this 👍👍

Hey Darin, on the next build you should borrow Dave's plasma cutter.

Hi there, can you please explain how the pivot system works under the tyre? what does it slide on ? cheers Brett

Me pueden compartir los materiales y medidas de corte en español???
Porfavor 😅
GRACIAS
