I used to have an Equal-I-zer hitch. However to be honest, I don't remember in detail the exact mounting scheme. All hitch systems however have a physical limit that restricts how sharp a turn you can make. If that degree of turn is exceeded, either something is damaged or forced out of adjustment. It sounds like the latter happened in this case. As you towed it further the rearward force eventually put it back into line again. I would suggest you examine your hitch for any bent components. If all is OK, then figure out a systems to keep from making too sharp a turn.
As far as I'm concerned it sounds like you have a good, appropriate hitch for your trailer and TV.
I'm sure someone, with more knowledge than I, will come along here soon.
