Okay, fellow RV’ers, I’ve gone through this whole discussion thread, made note of the additional stuff that some respondents said they’d like to see included, and I’ve compiled the following very lengthy report about our set-up. For those interested enough to read the whole report, you’ll notice I’ve also thrown in some extra data and commentary.
Truck (bought new in Jan ‘07): 2006 Ford F-350, Super Cab, short bed, 4X2, SRW, 6.8 liter gas V-10
Fiver (bought used in July ‘07): 2005 Sunnybrook Titan 30RKFS, with optional bedroom slide
CAT scale weights (loaded, while on three-week trip):
Steer axle = 3780 (620 under front 4400 GAWR)
Drive axle = 6120 (710 under rear 6830 GAWR)
Combined = 9900 (500 under truck’s 10,400 GVWR)
Trailer axles = 9840
Gross weight = 19,740 (1260 under truck’s 21,000 GCWR)
Truck without fiver attached = 7140 (includes two people totaling about 340 lbs, cargo of about 340 lbs, and about 25 gallons of gas in the tank)
Trailer weight = 12,600 (2400 under 15,000 GVWR)
Pin weight = 2760 (21.9% of trailer’s total weight)
Dry weights, after-market items, miles per gallon, and other details:
Truck has Lariat trim, plus several factory-installed options. Before adding any after-market items, it weighed 3.21 tons (6420 pounds), at a local (non-CAT) scale. Subtracting the minimal cargo, my weight, and an estimate for the gas in the tank, I figure the dry weight, as built and with an empty gas tank, would be about 5970 to 6010 pounds. As an aside, the Ford invoice and Certificate of Origin claim this truck’s shipping weight is 5799 pounds – and that figure is supposed to include 13 gallons of gas!!! For more detail on this issue, see my topic “Shipping Weight Understated”, which I’ll post in the “Tow Vehicle” forum as soon as I finish this response to the “weight” thread.
Three after-market items are a Line-X spray-on bed-liner (maybe 30-40 lbs?), a Fold-A-Cover bed cover (40-50 lbs?), and a Reese 16K Kwik Slide hitch (175 lbs?). Adding these items, plus 29 gallons of gas (about 215 lbs?), I estimate that the truck, with a full tank - no people or cargo, weighs about 6430 to 6490 pounds.
Truck has 4.10 rear axle ratio. Manually calculated miles per gallon figures are:
For highway driving without trailer: 13.8 to 14.9 MPG
For city driving without trailer: 10.5 to 11.8 MPG
For mix of city & highway, no trailer: 13.2 MPG
Loaded truck/trailer combo on Indiana and Michigan trips (minimal hills): low of 7.92; high of 8.95 MPG (These two MPG calculations were for the worst and best of five single tank fill-ups following distances where all miles were with loaded truck and trailer in tow.)
I’ve not yet taken this combo on a long trip with significant hills/mountains.
Truck is not a “daily driver”. Still has less than 7300 miles on it (just 1400 miles pulling). Don’t know whether mileage will improve as more miles are accumulated, or if the above MPGs are as good as it gets. To date, I’ve used 87 octane gas exclusively.
As for the fiver, the brochure lists a no-options dry gross weight of 9947 lbs. The optional bedroom slide-out adds about 400 lbs (per a Sunnybrook factory customer service rep). The unloaded vehicle weight (UVW), listed on the label in a kitchen cabinet (for this unit as factory optioned), is 10,781 lbs. The original owner added living/dining slide and bedroom slide awnings, a 2X2 hitch receiver and cross bracing, a main awning support platform, one Max Air vent cover, and a few interior and storage area items. I’m guessing the combined weight of these add-ons is probably 220 to 250 lbs. So, the dry weight may be as much as 11,030 lbs. Add about 40 lbs for a battery and 60 lbs for LP gas, and we’re up to 11,130 before loading it up. Of the 12,600 pound loaded weight mentioned above, about 300 lbs was for fresh water, about 30 lbs for LP gas, and about 115 lbs for two bikes, two heavy-duty cable locks, and the bike rack and its cover. All other contents loaded into the fiver total about 1080 lbs. That doesn’t include most of my tools, all the leveling blocks and boards, the king pin tripod, and my 30 gallon “Tote-Along”. These items travel in the bed of the truck.
The brochure shows a no-options dry king pin weight of 2090 lbs. The factory CS rep says that about 300 lbs of the weight of the bedroom slide is on the king pin – so that takes pin weight up to 2390 before any other options or contents are added. As stated above, my loaded king pin weight was 2760 lbs – and that’s with about 200 lbs mounted at the back of the fiver (bikes, rack, and receiver hitch). My fresh water tank is located just ahead of the front axle, so some of the water weight is on the pin.
The brochure shows a length of 31 ft 8 in. Our unit, with the optional extended pin box, and ladder at the rear, is about 33 ft 4 in. – with the bikes mounted at the back, about 35 ft. Total length of truck, trailer with mounted bikes, and with the sliding hitch in the “travel” position, is just a few inches under 50 feet.
The trailer tows level and there are about 6.5 inches between the fiver’s underside and the top of the “wind seals” (as they are called by Fold-A-Cover) – the strips mounted atop the truck’s bed rails, that support and contain the folding cover.
Trailer axles are rated at 6000 each. The 9840 loaded axle weight works out to an average weight per tire of 2460. I’ve not gotten individual weights on each trailer tire, but hopefully, no single tire is carrying more than 3000 pounds. The made-in-USA Goodyear Marathon tires are size ST235/80R16, Load Range D, rated for somewhere between 3000 and 3100 pounds at 65 PSI. No tire problems to date in my very limited use of this trailer.
With MOR/ryde IRE suspension, shock absorbers, the soft riding ST tires, and the way we load it up, this trailer seems to pull quite smoothly. In our limited experience, there has been minimal up/down or front/back jerky sensation – certainly, nothing annoying.
There. Enough said about our combo (probably, much more than enough said for many of you). I wanted to give as full a disclosure as possible – for the benefit of those contemplating a fiver. Hopefully, it’s been helpful.
