Did the OP ever respond after the 1st post? Couldn't entirely blame him if he didn't.
FWIW, having driven trailers of one sort or the other since '74....I don't balance the tires on the boat trailer (2 trips per year) or the sno-go trailer (dozens of trips but less than 50 miles each trip), but on the "utility" flatbed (w 16" rims), tires get checked for unusual wear at least once a year and are balanced if any issues show up...without unusual wear, they're balanced every 2 years or so.
FWIW, what the shop says does or doesn't need to be done is just one data point: if my experience or the experience of others whom I trust indicates otherwise, that indication often turns out to be an alternate data point to which I'll give more weight.
I’ve always balanced my travel or fifth wheel trailers , but never my utility trailers , nor have I had any issues not balancing them . They’ve never gotten a great amount of miles, the tires usually age out before anything , although my little 10’ flatbed to haul my inflatable pontoon boat gets a fair amount of mileage behind the fifth wheel, and back and forth to the lakes .
