Our Sunseeker 2300 Chevy sure pitches side to side a lot when we encounter any bumps at all while turning at slow speed, such as leaving a parking lot....

As others have stated, the difference in height can make a difference in rocking side to side. That A/C on top is about 7" higher than on your previous motorhome. A 2005 RVision Trail-Lite 213 was 10'-8" while the 2014 Forest River Sunseeker 2300 is 11'-3". You also have a much heavier looking cab-over. I'm fairly certain that your Trail-Lite gas tank was lengthwise and between the axles and so was your fresh water tank.

Handbasket probably has the best suggestion of varying the air pressure in your air bag. I would start by dropping the pressure from 50 to 40, then 30...until 10 psig. I doubt you need to be above 50 as that 4500 should have enough spring to hold your weight.
