Without a doubt I agree wholeheartedly with the last statement in the OP. Well, nothing beats free as it pertains to cash out of pocket. Since you both have experience with these type of hitches, and feel it is a good fit for the smaller Lance TT, all the better. Looking online similar new hitches were under $200, definitely a nice find for your brother.
Lance TTs are pretty pricey, personally I would be going with integrated sway control, but that's all we have experience with. We often travel by interstate and with the winds we experience in the four corner states where we do most of our RVing, we need sway control that could handle our larger TT. Hope the hitch works to his satisfaction, I'm know he will enjoy the solid build of his Lance.
