Whats your TV ? I just bought the 29 , have not even picked up yet . I have a chevy 2500HD set up for towing 4:10 and the 6.o gasser .I've decided to go with the Andersen WD hitch only weights 60 lbs no bar's or grease , i hear it does extremly well for no sway no bounce and good on WD . With this hitch you won't have to worry about 1000lbs bars and a hitch that weighs 200lbs . you can adjust the WD portion of the andersen lighter
Advertised TW for the base model is 1032lbs. That said, for your example, 487 lbs TW is not nearly enough to be safe. NOT NEARLY ENOUGH. Absolute Minimum is 9%
My tow vehicle is a Toyota Tundra 4X4 Limited with tow package. 381HP 404lbft/tq and a 4:30 rear gear. Rated to pull 10,300lbs or 17,400 lbs GCVW. It has a class IV receiver good for 1200lbs tongue weight

you have to remember that 487 is only if you have your cargo loaded with nothing else , add propane tanks full ,batteries and gear I think you'll be fine imo . I have gotton severl different weights from the dealer and forest river on TW , ranging from the 974 to what you quoted 1032 . I've gotten cargo from 2700 to over 3000 . not sure which is right . i assume you will carry more then just what you store in the garage ! the under bed storage can carry a lot of gear . if you add a 4000 onan gen that's another 174 . I see no reason you can't keep the tw around 800 or 900 lbs even with the 2000 lbs in the cargo . . but that's just me . i was more worried about the 4400 lbs axles then the TW . of course some have gone up to the 5200 lbs axles from what i have read here

Beg to differ. Theoretically and using the only math I have seen posted anywhere, putting 2000lbs in the rear reduces TW by 800lbs. Adding 1000 back ahead of the axles, put 400 back.

This is all HEARSAY. I want the real numbers

Well if this were the case then nobody can recliam lost tw when loading the garage with their toys . . These units our toy haulers are designed to carry the weight of a couple 900 ++ lbs motorcycles , atv or combos of the same in the rear garage .
So what your saying is the design is flawed and no one should carry anything in the garage over say 1000 lbs ? i'm putting my bike 900++ and my atv 600 ++ and have no concerns what so ever . i am concerned about over loading the entire unit . but not about tw . remember the unit is designed with axles set back quit a bit and weight fwd unloaded . loaded with all the goodies I believe the units are set up to handle this . again which is why the axles are moved way back and so much of the tt is out front of the axles

As it is now dry weight is apox 69XX lbs with a dry tw of any where from 974 to 1032 . if this were a standard tt with a dry weight of 69XX the tw would only be around 550 or 600 . if that . so we are well with in towing specs with 2000 in the garage and the remainder 700 in other goodies loaded weight fwd

Your exactly right northstar1960. The thing is, Everyone, everywhere quotes the 2.5 to 1 ratio which makes no sense if the engineering is correct. And, if the engineering is wrong, people would be having problems towing, right? So, show me the real numbers. Has no person weighed their trailer?

I do share some of your concerns . I had issues with the axles ratings of 4400. with a dw of 6968 , less any un-sprung weight of axles /tires etc say 700 /800 gives us total weight loaded 8918. exceeding the weight limit of the axles , However the TV is suposed to pick up some of that weight through TW transfer to the TV so the closer to a 1000 lbs tW the better it would seem .

GDavidHughes, First thing you have to realize is the number of 29 owners on this forum is few, but growing. I know what my 29 weighed as it left the factory. I would assume the 2015 (early) brochure was correct stating the TW. Until proven wrong, I will trust that it is very close. With so many variables, I frankly don't see how my weight (for instance) helps you. I don't have two goldwings or Ultras to load in the bay and what each of us would carry, especially water changes things drastically. Do we even know that my unit and your's has axles in the exact same placement; no, only the XLR guys would know this. And, I bet they are getting quite a chuckle out of our rambling and 'rithmetic.

That 2.5 to 1 TWR, we all have heard is more like 3.5 to 1 when the weight is placed about 4 feet from the garage / bathroom wall. Such as would be the case with two heavy motorcycles, side by side.... as far forward as possible.

So, its only geometry, dear Watson! But, you got me thinking, measuring and plugging all that into an Excel spreadsheet, which I am decent using. Not the ace, but not too bad. I can send you the spreadsheet if you let me know your email via PM, that is if you have the application.

If not, you can download a free viewer, but the idea is that you change the numbers and play with it to find weights and the important TW ratio.

I have attached three screenshots of the spreadsheet, for what their worth and if you can see them, maybe this will help.

Top one has 2000 in the garage (like two bikes side by side front wheel near the forward wall), 54 gals of water, and a paltry amount of other cargo that will max it out (276#) and has a 7.72% TWR. The middle one with 2000, 20 gals of water and maxed out; 7.71% TWR. The bottom 1500, 54, and maxed out; has 11.71 TWR.

When I put the best estimate of my typical loading, into to the spreadsheet: 1000, 20, all of her "stuff" and I am more than 1000 from being maxed out. The TW ratio is over 14% according to my "guess-tomater." I know when I drop it onto the 2500, the TW is substantial.

Anyone who wants to play with the sheet, let me know how to get it to you.

Another point, I'd like to make is that by plugging in loading in any combination, the 4400# axles and "D" rated tires were never shown to be anywhere near overloaded.

didn't you up-grade your axles to the 5200# ones ? what was the cost of that ?

Cost?, no cost. It was done by FR because some units, like mine, the axles hit the frame under load. And we expected a much higher cargo cap. of 4017#. We only had to ask, and FR didn't question. Officially my unit is still only rated to carry 2724 in cargo. I am sure mine will carry that 4000# in cargo, if I needed it to, but FR isn't saying it will. To do that, it has to have something like the 5500 axles.

It was shown: dry weight 6968, tongue 974, cargo 4017. Gross weight TBD. Math says the GVW would have been 10,985#. That would put 4620# on each axle, but the "D" tires are still under the limit.
