I can confirm that the handling on my DIY cycletruck was dire (terrible wobble loaded or unloaded) until I significantly reduced the size of the rack. Rides well now but cargo capacity is a lot lower. Still more stable than a front rack on a fork. Next cargo bike will be an Omnium style one with a small headtube up front and a steering linkage (is that the plan for yours @M_V ?)
Before and after.
I know Ahearne sorted the handling on his cycletruck by raising the rack. But now his rack's so high you could practically fit a 26" wheel underneath. blech
Cycle-trucks are cool, but once you get past the cool-factor they're an evolutionary dead end.
