Been a while since I posted.
The family and I just took the 33sw on a 2600 mile road trip with no issues. Even with the upgraded 3trax system I had installed 2 years ago, I still don't look forward to running the slide in an out. But no problems whatsoever on the trip. Ran it out and back in probably 12 times and once managed to smash a DVD case between the slide and the exterior wall after the kids dropped it behind the driver seat while we were driving and didn't tell me. The crunching sounds when running the slide out when we stopped made my heart skip a beat. Heh. But I ran it back in and out again with no problems.

Been exchanging emails with them and I might bite the bullet. They suggested going with just the 35hp Heavy Tow tune due to the weight of the coach. But it adds another 75tq and firms up the trans shifts. In addition to the tune, it provides a lot of useful real time data using all the existing factory sensors, such as EGT and such. I've had a couple DP Tuners for previous 7.3's and even with the conservative tunes the trucks would just drive so much better than stock. If I do bite the bullet, I'll report back :)
