I am not trying to be critical, I feel your pain, you have some major weight issues to deal with. You have made a major investment. The F450 is more forgiving, the RV suspension is not. There is thread after thread of suspension failures. I wish you luck in working this out.
We do plan on boondocking eventually. One axle is a bit more than 3% over (7,250 vs 7,000). We did a weighing a few months back of the entire rig, not wheel by wheel and we have lost a lot of weight. Foolishly I do not know where I wrote down the new weight but I will do it again when we leave here for pre-winter servicing. Remember the truck is over by 325 lbs and the one axle by 250 lbs. We removed almost all the weight from the frontmost storage bin under the front couch and a lot from thge basement. I am optimistic but if that isn't enough then we will do more. Thanks for reminding me to account for tanks, fuel and future solar next time.

The better turning radius is worth it too. I wish I went with the 450 vice the 350.

The turning radius alone was enough to put a smile on my face. Spending half my life in Florida where every destination (it seems) calls for a u-turn, and the other half of my life with me taking the wrong turn and going the wrong way!

Here is another view of weights.
Truck ready to hook up was 10,200 lbs but fuel was 50% so corrected GVW would be 10,360. This leaves a payload of (14,000-10,360) 3,640 lbs. Door sticker says I have payload of 4,613 lbs. That means our ready to tow stuff, people, fluids, hitch, dog, tools etc is (4,613-3,640) 973 lbs. It also means that the pin wt % needs to be 22% of trailer GVWR, BUT since trailer is overloaded we are actually at 20%. That % is acceptable but 25% is even better. Now here is the tricky part many don't get. Assume truck is NOT overloaded but is instead 100% loaded which for my truck and my loadout leaves 3,640 lbs of pin weight. Using the max tow wt of 27,500 lbs the pin wt could only be 13.24% which is in my opinion waaaaay too low. As a double check, GCWR is 41,800 and subtracting max tow of 27,500 leaves a truck of 14,300 (don't know how that 300 got there) so everything checks. I think what happens is that good folks think the weights are an OR situation when in fact they are an AND. That means you have to pass ALL the weight checks and we didn't even get into tire and rim specs. I didn't for my situation because I am still under the rear GAWR and the factory rims and tires are spec's for that axle. I just noticed that if I bring trailer down to it's GVWR then 25% pin wt is 51lbs heavier than now! The reason is I am now at 22.6% so to get to 25% requires either moving more wt from behind the axles to in front of them. That will not happen, the vast majority of the movable wt is in front of the axles. That might mean I am sitting nose high when hooked up and I need to reduce that. The problem is I need more clearance between the RV and the truck since I already damaged the bed cover when turning through a small ditch. That is a tradeoff I will have trouble deciding on although a bed cover is a lot less expensive than a blown axle on the RV probably leading to a write off. Imagine what would have happened if I had bought a 250 which only comes in a single rear wheel. The 250 is limited to about 2,000 lbs pin wt after deducting people, hitch, tools etc. That is HALF my actual pin wt!

What you are relating here SHOULD be given to EVERY RV buyer and pickup buyer looking to tow. If we gave it to the truck and RV salesmen it would go straight into the trash.

Maybe a simpler solution for you would be GET A SMALLER FIFTH WHEEL! Just kidding. Good luck in you quest.

Nothing so drastic, we just need to lose a bit of weight which we may have already done but I won't know for sure until we move to winter quarters about a half hour away and we drive right past the weigh scales. Keep in mind that the TV is only 325 lbs over and the RV is 250 over on 1 axle with the other 100 under. The entire RV is 1,570 over due to weight in front storage which we have since cleaned up. The purpose of the post was to show that even with a big truck parts of the rig can be over weight while well under on others. The big issue is the use of 'towing capacity'. That is a mostly marketing number not the key determinant. GCWR is far more important.

THIS information should be mandatory before people purchase truck or trailer. Sadly few check their capacities and think the salesmen know what they are talking about.

I have been telling people for years that the door sticker DOES NOT reflect what you can actually carry. The load capacity on the door is before all fluids, people, hitches, tools, dogs, cats, and anything else you can put in the truck. I have a 2017 F350 DRW Lariat and with everything in the truck I weigh 9500 lbs. The trucks 14000lbs GVWR - 9500lbs actual truck weight means I can put only 4500 more pounds in bed. My 2018 Montana 3120RL has an actual pin weight of 3000lbs. Not the 2200 - 2400lbs most people keep using. This is with only 2000lbs in the trailer. With a SRW diesel I would be over weight on load capacity, but not pulling capacity. These are all scaled weights BTW. Trailer is just at 14000lbs weighed and could carry another 2000lbs to max out its 16000lbs max weight rating. We sold our 2016 F350 SRW and bought the 2017 because I was at max or over for load capacity. Not towing capacity.

I daily commute in the DRW and find very little issues with parking other than the length. Driving it is easy as pie. Stability with the trailer is unreal and to tell the truth if I have a say about it; I won't go back to a SRW. I live in British Columbia, Canada. We have a lot of mountains here and some very steep grades. I thought my 2016 was a very, very good truck, but this 2017 is clearly better in almost every aspect. When Ford said this is the first new Superduty in 18 years, they were not kidding.

I also live in BC and got the F450 for a little more than $2,000 more to get the 4.30 rear end, the bigger brakes and class 4 parts but class 3 license fees. It too is my daily driver and it is legal width. It actually out turns all but a few stripped down F150's in the Ford lineup due to the wide track front end. The only issue is BC's love affair with small vehicle parking so sometimes I have to park further away but I am not in a hurry in any case.
What some folks don't appear to know is that you have to make sure ALL the weights are in spec, not just towing capacity. It's an AND not an OR.
The quick shopping checks are the trucks GCWR-trucks GVWR is the trailer GVWR. The door pillar sticker load capacity - 1,000 lbs times (4 to 5) is the trailer GVWR.
