If you ever get a chance take a picture of your setup, and post it. My son-in-law can weld and I have a stick and mig welder.

Have you found the weight for each axle with the unit loaded. I have the same unit, and I don't think you can safely pull either trailer loaded because the rear weight limitations. The tongue weight will be too much for the rear axle. In addition, your tires will be over their weight limit. How do I know all this, I have the same model and have been on the scales more than once to make sure. I wouldn't do it. I use an American Dolly with no problem.

IMO the Tongue weight is key in towing with a Class c..

My OEM hitch was 3500lb, 350 tongue, previous owner exchanged for a 500/5500 hitch..

Now the ratings when you add weight distribution bars will allow more tongue weight, check your documentation on hitch..

My GVW is 12K combined id 18K.. by ford chassis invoice.
and 12K/17/ per Winnebago tag,, they down graded IMO becasue of the addon frame..

I tow a 16ft 7K enclosed, average weight of trailer and contents 4200-4800 is normal. I have hit 6200 but it is rare..
My tongue weight is 450 ish. depends on how we load,, I dont use the weight bars unless I have it Maxed..

Blah blah.. IMO the E450 should do better than my old steed..e350

I only notice it even being attached is on hills it does hold you back LOL

The tongue weight is important but not the only consideration. If you are over your rear axle weight limit or over your combine 4 rear tires weight limitations, you are looking for trouble. These units because their engine can pull more than what the axles and tires can handle. People think that because they can pull somethings initially without problems, that is ok to forget about other considerations.

I mentioned eariler that my OEM build tag vs the Winnebag built tag as the rear axle load different,,.. Winnebago has it 800lbs less that fords .. I assume it is for safety plus the frame extensions etc....

If I use the hitch that came on my Rv with its load rating, I would never have bought the RV, 350 tongue and 3500lbs..

I just upgraded Hitch and stay withing combined load, I will check rear axle load next time I get to a set of scales that I can let trailer tongue weight only factor in..

Ford spec is before frame stretch. Won my is after stretch as built. That's the weight difference on the hitch specs!
Ford does not stretch the frames. They have specs for that, but its done by a shop that does it for the RV industry.

With my Class C, I happened to get the Ford spec for how to stretch.

i am going to chime in on this one since we full time, we started by wanting a class c but were not able to do a car and motor cycle and roll away tool box so we went to a 39 ft gas class a w 24 chassis with 8.1 liter.

next i found that the motorcycle lift to be done right it would need to have the over hang part of the frame re enforced at an added cost so with the cost of a blue ox system for the car the added cost to do the frame and the cost of the lift was higher then an enclosed car hauler.

now the class a comes with a class III hitch 600 tw and 6000 gtw but mh manufactures under rate to 500 tw 5000 gtw. however the mini cooper ,v rod, tool box and weight of the trailer exceeded the rating.

we spent an extra 1000 bucks for a custom dual anti sway weight distribution hitch still cheaper then lift tow price.

we then added a banks full power system and added extra leafs to the leaf springs and a safe T steering stabilizer

we also keep the fresh water tank (108 gal) full at all times and our rig came with 22.5 rims and tires since it is the w 24 chassis 3 option

Hi jon,
The sticker says 5000 lbs front axle, 9500lbs rear axle with a gross weight of 22,000lbs this is where the 7500lbs towing comes from.

nvs4602, I have known those numbers for over two years. However, these are helpful only after you take your unit loaded to a certified scale. Then you can find out for sure how much your unit weights, the axel weight, and how much is left available to you for tongue weight. I can tell you from personal experience that I found out that I didn't have as much as I thought. To avoid going over the rear axle weight, I only carry about 10 gallons of water, and half tank of gas. You need to find out what your weight, and how much weight you have on the rear axle. Then you can compare with the specs. If not you can find out over your rear axle weight and your rear tires weight limit that is less than 10,000 if yours have Michelins like mine. Just trying to be helpful. Avoid accidents.

311FS are rear heavy. Because of that I would not pull a trailer like the one you are describing. If you have an accident, you may be in big trouble.

I'll probably regret posting this "random" 311FS with a 29' aluminum trailer hitched to it I just so "happened" to see.

People think, because they saw someone else do it that's its OK. That does not mean its both safe and smart. I'd tow that with a super C!

Been there ,,,done it... LOL

My old short bus, 1994 E350, eldorad0 shuttle covered to RV , was owned by Marvin Paunch, Nascar driver.. He towed his replica 63 pontiac.. in an enclosed trailer over 100K behind this e350.. to shows and events around the USA..

Was it right.. no clue..
I have towed a 22 foot car trailer with a load and it handled perfect.. I scaled at 17800 combined or so.. Problem it was licensed for 15k up here in PA.. blah blah.. Even at the toll booth they bitched, as it ran their scales and my weight sticker was actaully PA class 2.. oops.. Paid the higher tool and moved on.. luck I only use that trailer 2 times a year ..

I said this before, my 96 minnie hauls 6200lbs out back fine.. That maxes me or puts me over a tad.. NO ill effects, I think it handles better with the trailer,, Sure fast stops have trailer brakes locked but .. she hold not on a dime but a nickle..

When I have time a friend is a DOT cop.. he has a set of 8 scales he uses.. when I am in town and he has time we can get real numbers when I am running "full"

the old rv short bus is behind.. the trailer i tow, 16 ft V. 7500 gvw
