Towing a 2013 White Hawk 28DSBH

Hello all, Newbie here. We are about to purchase a 2013 White Hawk 28DSBH, but before we sign the dotted line I need to make sure my TV will be able to tow it. We have a 2005 Ford F150 5.4L V-8 3.55. Manufacturer shows tow capacity of 7700# with 18" tires (CGWR is 13500). Truck originally had 17" tires (GCWR 14000) so I know I have lost some of the rear axle gear ratio and am trying to account for that as well. Sticker payload is 1508. Yellow sticker on TT is 5839 and I figure we would add 1000# to that number. If I figure the tongue weight at 13% of 6839 it would be 890 lbs. So I figured 1508-890=618. Weight of DH, myself and kids 450, leaving me with 168 for payload capacity. I am going to go to CAT scale next and get actual weight of truck. Will this work or should we cancel the deal? Upgrading to a bigger vehicle is not an option at this point. Of coarse the dealer was saying that we could tow bigger trailers and as I began to do some research I quickly concluded that it was not going to work which is why the White Hawk seemed to be our best option. This will be our first TT so I am welcome any and all advice.
Thanks in advance, Linda

Hi Smiley,

your best bet is to load the TV up as if you are going camping and head to the CAT scale. once you have the weight of each axle you'll be in a better position to make the decision of whether or not the White Hawk is a fit. Just remember that everything you added or changed to the TV has changed the payload that you are referring to, even your new wheels and tires. Lets see what the CAT scale says.

Ok filled up the tank and went with one child to CAT scale. Steer axle 3320, drive axle 2720 total 6040. Husband and other child would add approximatley 260 lbs. Did not really plan on putting anything else in the truck, but all in the trailer just to keep payload down. It does have a removable bed cover that is quite heavy on it probally 100-150 lbs that I could remove if need be.

Hi Smiley,

not sure what the GVWR of the TV is? The white Hawk loaded as you indicated with the WDH would be close to 7000 lbs.
Your TV loaded as you indicated would be 6,240 lbs....the tongue weight of the trailer @ 13% would add 910 lbs to your TV's GVW increasing it to 7,150 lbs. Your GCVW would be 13,240 lbs which is very close to your limit of 13,500 GCVWR. Again I'm not sure what your TV's GVWR is but you could be over or very close to it's limit.
Your are doing this the right way, knowing your actual weights will allow you to make the right decisions...just keep in mind that you must also satisfy the GAWR of the TV's axles.....most 1/2 tons Achilles heels are the GVWR's.

Linda,

Welcome to JOF

Great do-diligence on your part, it will insure that you end up with an enjoyable and safe TV/TT combination.

Your thought process in your original post actually is spot-on, but using the TV's sticker payload of 1,508lbs is based off the TV's curb weight, which may skew your usable weight results. Using a "13%" loaded tongue weight minimum is smart on your part with the 28DSBH overall length of 32 feet (enhanced TV handling)..., and your venture to the CAT scale was another good move......, now you have some real weights to work with:

(CAT TV gross weight of 6,040lbs) - (TV specified GVWR) = Weight Remaining for; WDH, loaded tongue weight, any other TV weight not accounted for (passengers, added cargo, etc.).

Your assumed loaded 28DSBH TT weight of 6,839lbs (realistic with a 7,500lb GVWR) = 889lbs @ 13% as you stated.., or 889lbs to 1,025lbs (13% to 15%). I would not recommend going below 13% with a 32 foot long TT.

Be careful using your TV's published Tow Rating of 7,700lbs, because it is also based on the TV's Curb Weight. Ref: http://www.jaycoowners.com/showthrea...uot-Tow-Rating

Towing a 2013 White Hawk 28DSBH

You are pretty close to your tow rating and gcwr. That would be my concern. Without knowing truck gvwr I can't say for sure, but payload numbers look ok.

My concern would be engine power and gear ratio. How much horsepower and torque does the that year 5.4 have?

As comparison, I just bought a 24fbs which has a sticker weight of 5,500 lbs. my 5.0 has 360hp and 380 ft lbs of torque, plus a 6 speed transmission and 3.73 gears. Towing my trailer the 200 or so miles I've towed, I am not sure I'd want to do it without the 6 speed trans or less power. The taller gears won't help either.

It might be ok, but you won't be setting speed records and you'll probably have to rev the nuts off it.

Towing a 2013 White Hawk 28DSBH

Looks like the 2005 model had the 3 valve 5.4 with 300 hp and 365 ft lbs. you should be ok as long as you don't expect blistering performance. I'd hesitate if you had the older 2 valve.

If it was me, I'd probably feel more comfortable with more room under towing and gcwr cap. I'd probably stick to something in the 4,000-4500 lb dry range, given the gearing and 4 speed transmission. Would be a little less "maxed out".

Smiley,
Some people say, to be comfortable, it's a good idea to not exceed 90 percent of the GCWR. Your numbers indicate with your estimate for loaded TT weight, you would be about 94 percent of the 14,000 GCWR. I have previously towed at 100 percent of GCWR and felt ok while towing in fairly flat territory, but I knew full well that mountain terrain would be a problem, and would at best require slow going on my part. I would say, a lot depends on your expectations for performance and the type of terrain you expect to encounter.

Of course you need to stay within the GVWR for both the TV and TT, as you have already been looking at. Another consideration, with that length TT, if you have the friction bar type of sway control, you will want two of them, one on each side of the tongue.

Smiley,
Here is an attempt to answer your question about tire size…….you say you went from 17 inch rims to 18 inch rims. The important question is; what is the difference in overall diameter of the two sizes? My guess is, the stock 17 inch rims came with 70 series sidewall profile, and your new 18 inch rims have tires with a 60 series sidewall profile. In this example, the stock tires would have an overall diameter of 30.6 inches, yet the 60 series on 18 inch rims would have an overall diameter of 29.6 inches. For this example, the 18 inchers would actually improve your rear end ratio by a small amount. Have a look at your tire specs for overall diameter, before you worry too much about any reduced towing capacity because of that factor.

David,
Yes the new tires are P275/R6518. Thanks for the info. We are getting what I think is a pretty good deal on this model $20,843 so I would really love to get it if we could. My DH's next option is the hybrid Jay Feathers that I am not very crazy about.

That seems like a good price! What are you getting for options with that?

The dealer said they would install a Dual Cam weight system. Another thing to research. Do I need to include the weight of that as well?

I think you do need to include that in the weight as well. Did it come with any options? TV, power tongue jack, roof ladder, hide a bed, etc? I would recommend the power tongue jack.

Yes it comes with all the options I have listed above.

That is what found for horsepower/torque. It is hard to find what we are looking for in the 4000-4500 lb range that will sleep 8-10. We really want to stick with a local dealer as well. I looked at a Coachmen Apex, same layout and about 450 lbs lighter but it is over 100 miles away and the Jayco seems to be better quality.

WOW, that's a great price. I got all the same options excluding the the power stabilizer jacks and paid 23,900 fees included.

That is the price for the trailer. With taxes, title, tag, fees, installed brake control ($150), and dual cam weight system ($1000) the total out the door quote is $23488. I think I can do better on the the weight control bars but have not gotten that far on the research.

Yes, allow about 70lbs against the TV's payload.

FYI, depending on the product rating the ship weight on a Reese Strait-Line WDH (with Dual Cam) is 70lbs to 90lbs.
