6500 is going to get a lot of trailer. I just looked and could buy a 22ft hyd tilt 14k trailer for 6799.99 locally.
A basic equipment trailer 18ft with ramps rated at 9990 priced at 2990. And the 20ft rated at 9990 for 3200.
Now understand there is a huge difference between a 20 ft trailer for 3000. Average and one that falls into the 4 to 5 thousand range but for an occasional use trailer the cheaper trailers are good deals.
I don稚 know many people who don稚 find enough use to justify owning a trailer. Just the other day my friend saved himself a huge towing bill simply by using his trailer purchased to haul his tractor when his wife痴 car broke down. Towing bill would have been ridiculous from his in laws to home but with the trailer it was just cost of fuel. Add to that mobility of almost anything you need such as wood for building, dirt for that yard work, mulch, stone for the driveway. Not only can you save on that extra charge for delivery of the big things but you get a small discount on the small things too. Add the convince of letting something sit on the trailer till your ready to use it rather than having to unload right now because you have to use your truck for something else and the cost really becomes justifiable quickly.
Now I know some people have things figured out differently and I am not trying to convince you you need a trailer. Just stating your dealer was nuts and only wanted to sell you more than you need or overcharge you not sure which but that for many like my friend who used to think a trailer would be a waste of money and would just sit, actually find that after they own one they find themselves using it more often then they imagined.
