Hi.
Yes the Toyota Tacoma has always had a ride quality that is noticeably bouncier than its competitors, which in my opinion right now, is only the Nissan Frontier.
Although they both use similar suspension designs, and similar off road components, the Nissan is "smoother" because it's heavier by several hundred pounds.
Eventually the ride may mellow out a bit, but it won't be anything drastic. I'm with the Toy4x4...the benefits outweigh the negatives. I also have Bilstein shocks in my 1996 Toyota Tacoma V6 4x4.
Hopefully I didn't offend anyone when I only compared it to the Frontier. But that's my honest opinion. The Ford Ranger is aged, and its Mazda cousin is the same. The Colorado is not up to par either. I am a Honda engineer and although we make the Ridgeline, I don't totally classify it as a truck.
On that note, you can test drive a Ridgeline. It uses a fully independent suspension which, gives it a bit of a disadvantage in towing, but makes up for it in ride quality.
