New member and seeking your collective wisdom.
We have a 1999 Explorer XLT, 4.0L SOHC and the 3.73 axle ratio. The kit is rated at 5,680lbs max towing capacity.
The Coleman Avalon (Highlander Series) has a GVWR of 4,600lbs and a UVW of 3,805lbs.
80% of the Explorer's 5,680lbs is 4,544lbs - slightly less than the Avalon's GVWR of 4,600lbs. Is this "extra capacity" sufficient to cover most scenarios?
Thanks in advance.
I'm not quite sure where your numbers came from... From page 171 of the 99 Explorer owner's manual, the 4.0L SOHC with a 3.73 is rated for 4535lbs (10,000 gross combined weight rating) and the 5.0L is rated for 4990 lbs (11,000 GCWR) whether it's a 4x2 or a 4x4.
Now, with the new numbers in mind, and knowing that Fleetwood's numbers are notoriously optimistic, 3800 is the dry weight.... figure another 40 lbs for propane, 60 lbs for the battery (generally not included in the dry weight), 30 gallons of water at 7 lbs/gallon for 210 lbs (more if you have a full water heater), plus another 200-300 lbs of gear (cooking supplies, food, clothes, bedding, etc) and realistically you're looking at somewhere around 4100-4200 lbs before you ever leave the house.
Oh, and you want to take the family too? Add another 130 lbs of wife, 75lbs each kid, car seats, diaper bags, coolers for brown-pop and ginger-ales, luggage, TV, etc... there's 500 lbs (or more) towing capacity lost.
Then there's the issue of weight distribution. Fleetwood trailers with front storage trunks are notoriously tongue-light. The '04-up designs are better than the 03.5 and previous models, but still not great. To get the 10-15% tongue weight they recommend, you'll need between 400 and 500 lbs of tongue weight, and that will
require a weight distributing hitch. Without it, I can guarantee you will be well over the rear GAWR, exceptionally nose-light on the tow vehicle, and you will NOT have a pleasant towing experience. Add up the weight of the hitch, and you've lost another 60-70 lbs off your capacity too.
And then there's the transmission... If you have a V-8, you shouldn't have an issue with power. With the V-6, on the other hand, it'll be anemic at best, and the 5R55E trans isn't going to like towing it in the slightest!! My prediction is that it wouldn't be long for this world.
I, too, go by the 80% rule when it comes to regular, long-distance towing. Around the block with an under-powere and/or ill-handling rig is one thing. Across the country on a National Lampoon Vacation type trip with the same rig would prove to be a nightmare!
My final answer: Your truck isn't the right tool for the job... There are other campers that are better suited to your particular tow vehicle, but that's probably not one of them.
There are some on this board of the mind-set that if you can hook to it, you can tow it. I'm not one of them.
