Advice for a newbie

Thanks everyone for all the great feedback and advice!!!

I've installed the Timberen springs and figured out that the spring arm socket nuts were really loose which was giving me little to no sway control. I can feel the difference of with the springs and was at a top of the spring/axle gap recommendation (1.5"). I may pop the spacer in there to see if it helps.

Regardless, I think my initial thought that i have a lot of trailer for the truck guess is right. It can be done but safety is paramount. I think I'll downsize to a shorter/lighter trailer in the spring when I have a better chance of selling this one. Until then, we're going to do some short 2-3 hour trips to some of the great state parks here in MO.

Thanks again!!!

Keep a close eye on transmission temps, even with a trans cooler. I speak from experience. For a while I towed a similar load with a 150.

You're probably at the top of your limit, but it's definitely doable. There's plenty that tow in the same ballpark with that truck. Timbrens will help take a lot of the bounce out of the back end. I have the Firestone versions and they work well.

Have a look at your tires. As a first step, if you aren't already doing it, you could try to air your tires up to the sidewall max when towing. This can give you a more stable ride than the pressures that are listed on the door placard. If the P metrics are just not up to task then you could move up to a P-XL or a LT-E. I'm at the same weights and P-XL works for me.

Putting Bilsteins at all four corners could also help control the suspension movement. I've put them on my truck and they've made a night and day difference loaded and unloaded. They're worth the cost. Although my OEM shocks were decent on my Dodge, the Bilsteins did a much better job.

Lastly, make sure you run your truck across the scales to verify that you're running fairly even weights on your axles. All the suspension enhancements in the world won't help you if your problem is that you're not carrying your weights properly.

Since you mentioned porpoising, and following the WDH instructions, I'm going to say you have too much tension on your spring bars. Take up 1 chain link less and give it a test. I think you've totally leveled your truck with the WDH, and that is too much. The instructions typically overstate the leveling stuff.

THANK YOU everyone for the insight!! Your experience is really helpful. I'm leaning heavily to going with a smaller trailer based on the feedback to this post and previous other threads on the topic.

After blowing 1 x transmission and trailer accident, I'm now a firm believer of having more (much more) Tow Vehicle than needed. If it were me, I'd get larger Tow Vehicle or smaller trailer. As mentioned by others, it isn't about towing using calculated math numbers. Its about safe towing.... For example, might be "within spec" using math numbers but add hills and wind resistance and its a major accident (or problem) waiting to happen.... If wondering, normal wind resistance blew my previous tow vehicle's transmission...

Hello Sausage King of...Missouri

Would it be possible to either borrow or rent a different truck (bigger) and compare the towing experience?

I have a similar weight and hitch setup and have no ill effects so far when towing. Our trucks are different, so maybe this compare will help decide if the issue is with the truck's abilities.

Note: I had the dealer setup the Equal-i-zer® Hitch

Its too much trailer. Spring will help, but I doubt it will help enough. Most conceder 6k dry the limit for half ton trucks. Better hope you don't have to trailer it home on a windy day.

You probably have 1,000 pounds of tongue weight on the truck. What is the payload capacity of the truck and what else is being carried?

A trailer of that size that has a cargo capacity of less than 1,000 pounds will almost always be overloaded after LPG, batteries, water, food, clothing, and misc. gear is loaded. Filling the fresh water alone will add over 400 pounds.

It might be within the trucks "tow rating"... But the "tow rating" does not account for how well it's gonna tow for you..

#7600 dry is way more than I'd want to tow with my Max Tow F150, but that's just me... :)

I'd tow a trailer with a GVWR of #7500 with my truck.. But I've towed trailers of all sizes and weights with a variety of vehicles since the mid 80's so I know what I like to tow and what I don't like to tow..

Good luck!
