On 10/7/2018 at 1:38 AM, OnlyCoolCarsTX said:We had a similar situation towing our 4 door Jeep with our 26’ E450 Born Free Class C.
We eventually ended up with bigger anti-sway bars front and rear, A rear track bar, and a big steering stabilizer. I don’t regret the money spent because I’m kind of a handling snob coming from sports cars...BUT...
Before you do all that, get your rig and your truck to a reputable suspension alignment facility. I had our rig aligned but I didn’t know the alignment was not correct. That’s when I started throwing parts at the problem. When I still wasn’t comfortable we got the rig to another shop and we discovered the alignment was way off. Unfortunate because the first shop had been highly recommended.
When we got the alignment corrected it was so much better. They then checked the alignment on the Jeep. While the alignment was technically within the spec it was on the borderline. They were able to adjust the tow and caster to make the Jeep track straight versus hunting back and forth. We went from thinking we were going to die towing the Jeep on our first trip to a 5,000 mile trip this summer with no stress. Bonus, the Jeep drove and handled way better in just normal driving. The “bad” alignment was like that from new.
Spend the money on alignments and then decide from there what you need next. Make sure the shop can provide before and after alignment printouts and that they can explain how those numbers are affecting your handling
Hope this helps. Sorry for the long post
Thank you so much. Very helpful. I will do these things and let you know how it goes.

Great suggestions - and thank you all for replying. The curb weight of the F-150 is right about 4800 lbs and the length of the RV is 25 feet. Wilde - I will definitely do that search.

Thanks Wilde .... I did weight the RV .... Steer Axle 4020 lbs, Drive Axle 8880 lbs, Gross Weight 12,900 lbs. I guess I should weight the truck as well. I was thinking a beefier rear stabilizer, sway, and shocks might help. Thanks for the guidance.

Thank you. This is great information. I have thought about several of these items. The tow bar is mostly level and I rarely travel full tanks. In most cases I travel with 3/4 full fresh water, but empty black and gray tank. When I purchased the RV .... I did get a full front end alignment. This made a huge difference in steering and managing the RV on the road. It actually made driving the RV rather enjoyable except when I was flat towing the truck. When I have the truck hooked up to the RV ... I can generally get to about 50 mph without too much trouble. Any higher than this and I begin to feel a sway in the back. The sway is limited, but it makes me nervous and I am thinking this should not be happening. I cannot imagine towing the truck for 300-400 miles or more with that sway. This is the reason why I posted here thinking maybe there are other options. I have seen plenty of class C RVs towing a lot more weight than I am flat towing. Anyway - I appreciate all the advice and help so far.

Thank you for your reply. Definitely sound advice. I agree the length of the truck is most likely the issue - more than anything else. I have considered trading for a jeep. So from your perspective, beefing up the rear suspension is not going to make a difference? Thanks again!

Hello everyone - new to the FMCA forums (new member). I am towing a 2017 4X4 EcoBoost F-150 behind my 2018 E-450 Class C ... well - let's say I want to tow it, but the sway on the back end is pretty significant when I get up to highway speeds. My question to the group - is there a rear suspension sway bar or system I should consider installing to tow this truck or am I asking to much of the RV. The weight on the F-150 is just at 5,000 which is what the RV is rated to tow. I have a blue ox tow bar rated at 10,000. Any suggestions on how to proceed would be good. Just so you know - I have considered trading to truck for a car, but I really hate to give up my truck. Thank you. Patrick
