    Best Hitches Made
    This hitch replaced an old one I had to put a bolt through to keep it secure. It had come loose once but I was lucky the safety chains kept it with the truck but the big dent still remains in the fender. Bulldog hitches are simple and I no longer worry about whether the trailer is securely attached to my vehicle. I just cut the old welds, ground everything, smooth, welded the Bulldog in place, added some spray primer, (the whole trailer will get paint when it warms up), and I am ready to roll. Both my trailers have been modified with Bulldog hitches.
