Hey Rick. Your 2025 Thor Chateau 27P was built on either a 2023 or 2024 Ford E-450 class C chassis. I saw you were looking at sway bars so I went ahead and found the parts you'll need. The recommendations I listed below fit both the 2023 and 2024 model years:
Front Sway Bar - Roadmaster Front Anti-Sway Bar w/ Adjustable End Links item # RM-1139-189
Rear Sway Bar - Roadmaster Rear Anti-Sway Bar - 1-1/2" Diameter item # RM-1139-147
Steering Stabilizer - Safe-T-Plus Steering Stabilizer with Mounting Hardware Kit - Custom Fit item # ST98MR

Hi Rick & Jerred - I installed the Roadmaster Front Sway bar (RM-1139-189) on an Entegra Odyssey RV which sits on a 2024, probably a 2023 manufacture date, Ford F-450 chassis about a year ago. I don't recall any issues with the installation, i.e., easy install. I also installed the Roadmaster rear stabilizer Jerred recommended. I did not go with the Safe-T-Plus Steering Stabilizer but rather the Roadmaster steering stabilizer (Reflex steering stabilizer, RBK24) . Nothing wrong with the Safe-T-Plus. It gets excellent ratings for a zero-steer stabilizer. Being somewhat lazy, I stuck with a standard stabilizer vice any model of zero-steer in order to avoid the extra step of adjusting the zero-steer set-up. I do not know what problem(s) Rick is trying to solve, e.g. sway, tracking, bouncing, etc., on his RV rig; however, sway bars and steering stabilizer are good places to start. If driveability issues persist, recommend considering enhanced rear springs (my RV came with Helwig rear spring boosters). Upgraded shocks and springs, particularly on the Front also helped. I eventually went with Bilsteins and Sumo Springs on the Front. Oh, and most importantly (strongly recommended by Roadmaster techs) get the RV properly aligned. After adding all the weight in the back, the front-end alignment is typically pushed out of shape and is usually something ignored by RV manufacturers. Recommend either a Ford Truck Center or a shop that works on big rigs to do this adjustment.......normal racks used at tire centers cannot handle an RV. Sorry to be so verbose on this issue. I went through several iterations of upgrades before I eliminated the white-knuckle experience while driving the Entegra. Other RVs may not experience the same issues I had with the Entegra.
