hitch and receiver

Hello, im part of a team of students in a mechanical engineering design class at Purdue univeristy and i ask anyone and everyone here if they could fill out this quick survey so we have some sort of marketing data to begin our semsester long project

theres a couple typos on there and we appologize for it, but to fix it would mean to reset the data we have already collected and hence not worth our time. I appreciate everyone's cooperation and may you all have a good day
