We buy almost all of our RV related products from Amazon and Walmart. If we don't need it right away, we get it from Amazon (have Prime). If we need it right away, we take a drive to Walmart. We also live less than a mile from Coastal GA RV Resort. They have a pretty decent assortment of RV related products. We have purchased a few small things from them.
I always take negative reviews with a grain of salt. If a lot of people were complaining that the tow bar didn't come with cables, then there's a good chance they company doesn't sell them with the cables. If one reviewer wrote it, it was probably just a one time issue. Amazon's customer service is very good, I'm sure they corrected the problem with little hassle.
