Not trying to be preachy or get in your business, as I am only trying to be helpful. Based on some of your comments in your posts, I wasn't sure if you were aware of your Expy's payload capacity or what kind of issues an overloaded TV can present, especially when pulling a TT the size of yours. Were you able to find your yellow sticker and verify your payload?
Just with the bike accessories and your family, you've eaten up 703 lbs of your available payload. Assuming your TT is loaded for travel at 8k lbs (but could be more with a family of 6), then your hitch weight is in the area of 1040 lbs (8k * 13%). I believe gas weighs around 6 pounds per gallon, so assuming a full tank in your Expy is 25 gallons, that's another 150 lbs (could be more as I have no idea how big your fuel tank is). So, when you are hitched and ready to leave, you're already at 1893 lbs of payload when you pull out of your driveway. And this does not include the dog, tools, firewood, kid's electronics, or any other camping supplies or cargo that may be in your Expy.
As mentioned, I had an '07 F150 with a payload capacity in the neighborhood of 1500 lbs (don't recall exactly now), and I would be shocked if your Expedition had a higher payload rating that my previous F150. When I ordered my new Windjammer last year, I didn't even wait for it to be delivered and hook it up to my F150 to see how it would perform. I bought the TV I wanted one day, and the very next day, we we went and ordered our WJ. Could my F150 with the 5.4L and 3.73 pull the Windjammer? With a towing capacity over 9k lbs, of course it could! But, I wasn't concerned about it pulling the weight, I was more concerned about it stopping the weight safely, if I ever got into a situation where I needed to stop or slow down abruptly. Knowing how I load down the back of my truck with firewood, camping chairs, grill, dutch ovens, inflatable kayak, EZ UP awning, sewer bucket, dog pen, etc., even with a family of 3, I knew I would be over my F150's payload capacity, not to mention I went from a TT with a 700 lb hitch weight, to a TT with a hitch weight over 1k lbs so that was 300+ lbs of additional payload as well.
Don't get me wrong, there are many folks who tow a TT the length and weight of yours and mine with a 1/2 ton, and without any issues, and they'll tell you that it "tows great" or "don't even know it's back there", and for most I am sure it does tow just fine. I would offer though that many of these folks are over their payload and don't know it, or are over their payload and don't care. I would also offer that most will never know the impact of being overloaded until it's too late. Ok, I am getting off my
Whatever you decide to do or not do, at least be informed, so you can make a knowledgeable decision. The first TV I bought to tow my previous TT was an '00 Expedition. However, I was uninformed about axle ratios and GVWR's, so I didn't understand why this big Expedition truck with a 6500 lb tow capacity struggled to tow my 6k lb Outback. I towed with this combo for a few trips over about 3 months, til I learned about axle ratios and GVWR's from good advice I recieved from others on various RV forums. After those 3 months, I sold the Expy, took a $900 loss, and bought my F150. Kind of an expensive lesson to learn, but worth it in the end.
