I guess I just don't get it. If you have something heavy to tow, like an RV, why would you buy a 1/2 ton truck that can't handle the job and requires helper springs or air bags? You all know that no matter what ad-on's you install you do not raise the GVWR of your vehicle, or make it safe to tow where it may not be in the first place.

I have a 30" travel trailer that weighs in at 9,500lbs GVW. I had to hook it up to my F150 to move around my yard because my regular tow vehicle was not available. I can tell you that I would not tow it any long distance with my F150, it just can't handle it (and I have the max tow package). Here's what I have used to tow my TT for the past 10 years. It does the job just fine!!!

First- terms like "half ton" are out datted. The current F150, with a payload of 1450 for example, is a 3/4 ton! 1/2 ton implies 1000 pounds.

Second- even with a load of 1000 pounds in the truck that has a cargo rating of 1450 lb, will make the OEM springs to compress, causing the bum to sag, and the nose to point upwards thus offloading the front tires. This creates an understeer condition, as well as badly aimed headlights! Adding bags, or springs, may not increase the GAWR, but that is not the point here. 1000 is less than the 1400 rating (or 3600 lbs on the rear axel is still less than the 4000 rating), the addition of the extra hardware keeps things more level. In my opinion, that's good planning.

P.S. Here's what I tow. With 3000 lb Supersprings installed. Notice how nice and level she is.

That's a nice rig there. However, I just know what I know from experience. I can drop the tongue of my TT on the hitch on my Excursion and put 100% of the weight on it (~1000 lbs) and it will sag maybe 1-2". I tried this with my F150 and as I was lowering my tongue jack (it is electric) the rear if the F150 was getting so low that I thought I would break something if I went any further. I had to put my spring bars on it just to move it around my property where with the Ex I would have just left it on the ball with nothing else. Surprise!!! they are both rated at ~10klb!! Also the 5.4L in the F150 is way underpowered. I had to really step into the gas just go get moving (I guess that was the 60 lb/ft that the F150 is missing compared to the V10 in the EX).

Please do not get me wrong, I really love my F150, but I know it's limitations. In no way do I ever think that it would replace my Ex. I would get an F350 if I needed to.

Platinum Sean, I notice you have the 5.5ft box with the 5th wheel. What hotch do you use? Have you has any problem with the trailer getting close to the cab when you back in? I have been told numerous times that short box is no good for 5th wheel. Any hints or advice would be appreciated.

The newer F150's to get their softer ride have fairly weak rear springs. Add any trailer with say 500 lb. trailer tongue weight, and the rear sags so much, I'm now skylighting with my headlights. I looked into the air bag system and supersprings. I ended up putting supersprings on. They don't affect the ride until you are loaded. Cornering seems to help with a load in the back. The only negative I have is I get a clank everytime I go over a speedbump at work. I've been told I have something installed wrong but looked at Plat Sean's pic's and are setup the same. Maybe my c-clamp is messed up.

I liked the air bags, but would want an air system installed. With all that was more money and more things that could go wrong. I installed mine in just over an hour, had them now for 18 months and would get them again.

I have a Pullrite 12K. It slides back 22.75" when required. These are very expensive hitches. Another option is a Reese Revolution which attaches to the trailer moving the kingpin forward, in essence, doing the same thing as the slider.

It can be done with a 5.5' bed. I am livnig proof

I have a FX4, 6.5 box, max tow pkg. I've had 1000 lbs of dirt in the box and was impressed as to how little it sagged. My travel trailer is a 27ft with 750 lb hitch weight, and it sags more than the dirt did, as well as lifting the front, due to all the weight well behind the rear wheels on the hitch. A slight assist from my weight distributing hitch and all is great. I'm coming from a 3500HD and am impressed with this F150' s hauling ability so far, realizing it is a much smaller truck and isn't meant for mega loads.

I added Timbrens to mine about a month ago. So for, I like the unloaded ride. I haven't put my camper on yet.
