Very nice............Love the crash dummy.
Have you thought about a leading link front end?
Normally, you run higher, wider handlebars with a sidecar, makes wrestling it through turns easier. You also usually need to stiffen up the suspension front and rear.
Well, you guys were right! The car with no one in it, or just the 70 lb dog, is fine. Put a full-size adult in it, however, and it becomes a handful! Still reasonable when going straight, but definitely an arm-wrestling match on a twisty road, or with a lot of turns around town.
If the car remains attached, I will definitely need to look into a leading-link and the wider bars.
I did have a tank-slapper that lasted several seconds, too. No passenger, just me on a 20mph road, coming off a corner. Couldn't accelerate out of it, finally had to slow down to 5mph to get it under control. Never happened again, but it was not pleasant.
Here's the boy taking his 70 yr old grandmother for a ride!
