I asked a specific question about the brake parts for my camper, I didn't understand how to use the website, after submitting the question I kept searching google and found infact the site does have the answer to my question about what brakes I need. Support sent me a response stating I have to go through all this work to determine what I need? All the answers were from people like me asking the same question and getting a helpful answer! I'm going to buy from somewhere else because of I had actually gone through what the support person told me it would have been hours wasted or $$$ spent on a Mobile tech I did not have to spend! Carful with the help you get from Etrailer this was the result of either laziness or ignorance, either way it's bad Business.
