So, time delay or proportional? I'm at my wits end because everyone is giving me conflicting information. The guy making my trailer is also a hitch installer and he says time delay is what he recommends. What do you guys have and why? What exactly is the difference between the two? I'm thinking the proportional is exactly what it sounds like but, I thought I would run it by some of you guys here. Besides, my trailer won't be ready until July 14th anyway.
