Really not a big deal but take it loaded to a weight scale and make sure the rear axle rating is within its limits, mine is towing. Well within the limits. But you should check. I use the bunk up front for a lot of stuff and I also load the Jeep down with gear.

Also the air bags in my experience should be at least 70-75 psi for flat towing. This also transfers weigh to the front axle.

Btw it tows 5500 lbs fine. I was able to accelerate up Jellico in Tennessee. Probably wouldnít do as well out west.

If you want a vehicle with a greater tow rating, then buy a vehicle with a greater tow rating.

In almost 6 years on this forum, I've yet to see anyone on this forum provide a manufacturer-endorsed "weak link analysis" supporting either towing or payload capacity for any motor home or tow vehicle. Of course, there is some safety margin built into every rating. But again, no one knows what it is.

Anything you may do to a substandard vehicle to increase it's towing capacity will be purely guessing on your part; hopefully you guess correctly, but chances are not good.

I didnít change the tow rating on the vehicle, just the hitch tow rating the e450 is already capable of 7500 even when it has a 5000 lb hitch. And the manufacturer did do a weak link analysis on that 5000 lb hitch believe it or not.

I found this thread: http://www.forestriverforums.com/for...n-57904-3.html

And in that thread I found this post from BClemens:
Quote:
We did nothing really different. Ford increased the GCWR back in 2010??? GCWR minus GVWR equals 7500lbs. We use a full frame extensions (same height and thickness steel that ford uses) all the way to the back. No departure angle (formed steel, smaller height in the back). This allowed us to use a 7500# hitch instead of a 5,000# hitch. Tested our 5,000 first, made some minor adjustments, retested, passed, sticker it for 7,500lbs.

We don't buy a different E450...we simply utilize the capacity they gave us. Of course it has to be tested, which we did and it passed.
So, I think I'm fairly comfortable thinking that it is likely the change from the 2013 E450 chassis Sunseeker to the 2014 and newer Sunseeker is a higher class of hitch.

So, if I decide I need more than 5,000 lb capacity then I will just upgrade the hitch.

Sounds like the frame/hitch/extensions are your "winner", but I wanted to point out that transmission and rear differential ratios can also effect towing capacities.

Nothing anyone has just posted above is a WEAK LINK ANALYSIS, it is merely hearsay regarding rated capacities for various vehicles and nothing shows what the limiting component is for any specific vehicle and it's rating.

And a hitch is not a frame, an axle, a drive shaft, or a _____.

When we do weak link analyses for, say, a motor operated gate valve in a power plant, we can tell you EXACTLY which part is the weakest and will fail if the drive train is overloaded.

No one has shown a weak link analysis for the OPs vehicle. Someone has mentioned similar units, but do we know they are identical? Maybe. Maybe not.
Someone then building an RV on top of the chassis adds further uncertainties.
Unless the vehicle manufacturer has endorsed an increase, YOU are guessing.

So I'll stand by my statement in Post #27. You can do as you like, but unless you are the manufacturer, you are not qualified to increase the rating.

420 lbs of torque? In a 14,000+ pound vehicle? Seems like they could save a lot of weight by taking that big block V10 out and put a 3.5 EcoBoost six cylinder in and get more power at the same time. Seems like adding 5,000 pounds towed weight would make the unit more of a rolling roadblock than it already is.

I agree you canít change the vehicle, axle ratings, tire loading, GVWR, and GCVWR all need to be followed. The point is, if the vehicle he is looking at has a GVWR of 14500 lbs, and a GCVWR of 22,000 lbs and he, like all of us, is careful to stay lower than the maximum axle rating(s), and lower than the tire weight capacity, then an upgrade to a 7500 lb rated hitch provided by Forest River is legal and acceptable in my opinion.

We all know the weight on the rear axle of these vehicles is the ďNormalĒ problem area if there is going to be overloading.

Iím as anal as anyone I making sure these ratings are followed. My JGC is only 200-300 lbs over the 5000 lb rating and I researched this issue carefully and upgraded the hitch before flat towing my loaded JGC. I have bikes, kayaks, tools, air compressor, floor jack all carried by my JGC and Iíve taken a lot of weight out of my rear compartments and moved them forward or in the JGC to give me more safety factor on the rear duels. Iím also thinking of upgrading all my tires to the General Grabber tires that have a 90 psi rating and higher load carrying capacity than the Michelinís giving additional safety factor not to carry more weight on the rear duels.

Iím not a person who believes going outside the manufacturers rating is ok. And Iíve been frustrated by manufacturers building 3/4 ton trucks that are the exact same as a one ton truck except for the extra leaf spring, and canít be re-rated after adding that leaf spring later on and and have the one ton carrying capacity. To me this is a rip off.

But at least since 2012, when you buy a e-450 RV from forest river most of those vehicles have the same rating. Now even though I could tow 7500 lbs on the Sunseeker, Iím not in a hurry to hook up my Dodge 1500 Ecodiesel to the Sunseeker. It weighs 6400 lbs. That would probably be doable but not fun to tow.

It's nearly impossible to change the tow rating. You could contact the manufacturer. If they would approve it which is doubtful because of liability issues. Then you would have to get approval from the state from which you live in. I would just have a 10k hitch installed along with beefed up frame rate ill l s and go down the road as long as your not over gross.

The state doesn't care about the tow rating, neither does the federal govt. They only care about GVWR/GAWR/GCWR.

Calculating max tow rating is simply GCWR minus GVWR.
