Congrats on your soon to be 38t.
Most w-24's come from factory with exhaust in front of rear wheels but some MFG's cut duels to single pipe. Your coach shows in rear of tires.
Most people will say load your coach balanced than get it weight and adjust tire pressures and drive, drive, drive than if you need a trac-bar get it. The 24 chassis has alot of upgrades since my w-22 with better improvement towards the ride you may fine that you do not need more add-ons.
Henderson does make bars for the rear exhaust if you need it.
