2003 Toyota Tacoma SR5 review from North America

2003 Tacoma PreRunner quad cab. After repeatedly finding water at the right rear floor board I conducted some self-diagnosis. This had not happened during the first 1.5 years of ownership. It turns out that because I now park on a grade, heavy rain flows along the lower window seal aft and down into the door. The water exits the bottom of the door at the aft weep. However, the flow is strong enough to overcome the door seal adjacent to the weep and enters the vehicle. I have no explanation why it only occurs on the right side, but using a hose to apply water to the window seal while I am inside with a flashlight, clearly pointed out the culprit. I haven't yet come up with a solution.
