No doubt your new frame will handle the weight overall but where the weight is located may introduce handling issues.
Andy has it right about the moment arm, which is the cause of this.

With a genset in front and a bike in back you are talking about significant weights a good distance from your trailer's pivot point. 600# would be getting near 10% of the total trailer weight. That means your going to have quite a bit of energy tied up in the angular motion (sway inducing) of the trailer.

You can compensate somewhat for what this will do but I know from experience, especially with the participants here, that efforts to discuss that rationally is likely to create an overwhelming urge for censorship. Been there, done that, dissappointed in the moderation I have seen all too often. Important topics that cannot be discussed.

This is a dynamic that I hadn't originally considered, I was thinking from a fire safety standpoint.
I'm picturing some of the roads that we have out here in CA. Even without added weight front and back, often times with certain vehicle combinations or lengths you can get a lot of induced porpoising from the expansion joints in the concrete roadway. If you throw the added weight on each end into that dynamic as a force multiplier you could be in for some serious problems in terms of handling and structural integrity.

What about this setup?

I can place the single Honda 2000 behind the LP tanks. The battery top is very thick and seems strudy. Weight is 47lb. plus fuel. I'll convert to LP for safety reasons. Put brakets up for security and easy removal. I ran the 11,000 BTU A/C on my 25SS and gen with eco switch off pulled her fine. With the gen cover on the gen actually blends in with the 22SS.

Also, What about moving the electric plug to the front and running the 25SS A/C on while underway for the dog? The ride actually apears nicer than the Ford Supercrew. The dog is always asleep when I open the door and is up on the forward couch.
The side clearences are not great, maybe 2 inches on sides, plenty on the front and back. I placed the exhaust to street side and kept the windows closed. I would never sleep in this configuation due to gasses. I will install a corbon monoxide detector as well. I also ran the unit for 30 minutes and the sides of the gen or 25SS did not get warm at all. Another good note very little vibration inside the coach while on, less than a newer SOB class C with it's gen on.

You asked?

It appears you have enough hitch to tow the Queen Mary.

The torsion bars for your rig, should not be rated at more than 500 to 550 pounds.

Anything in excess of that will cause front end damage.

You must allow adequate flexing. You have already severely reduced that with your choice of a tow vehicle.

Another step would be to remove the overload springs on the truck.

Then, you would have a chance of not damaging the front end of the trailer, as well as not shaking the generator apart.

Additionally, you should have a sway control. Your photo's don't show any.

Andy

Thanks for the tips. I thought the equalizer provided 4-way sway control. The ship is very steady in crosswinds and when big trucks go blasting by. Thanks again, James

Try riding, but be careful when you do, in the back of your Airstream at 60 to 70 miles per hour, for about 30 minutes.

Then please, report back as to it's stability, or lack thereof.

Woohoo, sounds like a fun E-ticket ride. No thanks.
Side note: it's interesting how many folks no longer know what an E-ticket ride is.

In this case the "E" ticket ride would probably be "Enlightening" instead of "Entertaining."

On the other hand, perhaps some would consider the wild ride as "Entertaining."

Then, I am sure, there would be more than a few that would say "Enough already."

What would we do without Disney?

Better yet, take a video camera along for the ride so we can all watch.

Anyone seen the videos of the school kids in the back of a bus flying around on bad roads - got a feeling this is the same effect on the trailer.

Isn't the Supercrew a half ton truck? I thought that was a 4-door super short bed F-150. If so, maybe you need like the medium weight bars? Does the Equalizer have different weight bars? I got their DVD but don't recall if it was one size fits all or if they have different ones like the Reese.

I still think the Hensley (sp?) is the best by design, but they sure know how to charge. I'm surprised Harbor Freight hasn't made a green copy of it and sold it for $200.

Ford has announced what some Airstream owners have been looking for.

It's a 450 Super Duty. Will carry 6000 pounds (3 tons) in the bed alone.

They haven't published yet the allowable towing or allowable tongue weight.

But they breifly said that you can tow 24,000 pounds.

Gosh, maybe it will handle 2500 pounds tongue weight too.

I always figured that someday, we would have to use "railroad track" for torsion bars.

Wonder how much a friction type sway control, will bend the A-frame?

Mama mia. What will they think of next?

Andy

Sway control IS built into the Equal-i-zer brand hitch. It doesn't need anything separate.

Geeze, don't you Reese people keep up with other/newer hitch designs?

Hi James (paxflyer) - welcome to the forums! I have the same trailer, hitch, generator and possibly truck (F150 Supercrew) as you.

- Your Equal-i-zer does provide friction sway control built-in. Equal-i-zer hitches come in 4 models with tongue weight capability of 600, 1000, 1200, or 1400 lbs. It looks like you have the 1000 lb setup (same as mine). Airstream rates the newer 25SS tongue weight at 720 (plus options and "variable weight") - so the 1000 lb setup appears correct for your application.

- I think Andy assumed that your truck is an F250 or F350, and is concerned that a stiff truck suspension plus heavy duty weight distribution bars will damage the trailer. However, perhaps you have an F150 Supercrew (same as I have), which has relatively soft rear springs so this problem may not apply to you.

- It would seem that placing the generator on the battery might work... it only weighs about as much as another battery. Also, I wonder how placing it there could be a problem, but placing inside the trailer about 4 feet back would be okay? I don't know the answer here, and will not recommend anything. I bring my Honda EU2000i in a large Rubbermaid container inside the trailer.

- Be careful running the A/C off the EU2000i - It may start, but a voltage drop upon startup could fry the A/C over time. You should check this with a digital voltmeter. Also, the output of the Honda will decrease under Propane power.

Thanks Dan, Yes I do have the 04' F150 Supercrew Lariat (nice truck) and the 1000 lb bars. I should set a video camera up and take her for a ride. The axels and tires make the 25SS appear to have a great ride. The 13 year dog (Golden, who by the does not ride with a seat belt in the truck either) has lots or room in the airstream is never frazzeled. I do have the good govenor voltage and freq monitor. This gen to date been rock solid in freqs and volts, 120V and 60hz.
I do wonder if anyone has moved a electrical plug to the front for this purpose and what problems were encountered?

Thanks to all,
James
