I'm not Alison but I also have a 2018 Expedition. It's my first Ford vehicle. Like you I was never really interested in their offerings, but I think the new Expeditions are wonderful vehicles. It handles everything we throw at it, not just towing but from an everyday life perspective. I love having three rows that can all seat adults comfortably. Creature comforts are all top notch, and after 10 hours in the saddle I don't feel sore. 400 hp and 480 lb-ft of torque are nothing to sneeze at. Towing over grades at high altitude is so easy it's boring (which is just how I like it). But I still get 19mpg in combined driving (average over 13,000 miles) and 12.5 mpg towing the Ollie (average over 4500 towing miles). I haven't done any serious offroading in it but on normal forest roads, even rutted out unmaintained ones, it has no problem whatsoever. Clearance is fine. As with any vehicle, choosing a good line is still the most important aspect for success. If you were navigating a rock garden you may be wishing for a different car, or a lift, but I don't do that anymore.

This is the slide I bought 6 years ago. It has gone thru several iterations of build in the two different pickups I’ve mounted it in. It has two different levels (as I built it.) You do have to drill to mount it. Both in the slide and the bed. If you are handy and doing it yourself this probably won’t bother you too badly.

[postquote quote=175221][/postquote] I agree about doing it yourself. [postquote quote=175233][/postquote] The video I watched on the CargoGlide install shows them drilling holes. Not something I’m looking forward to doing to a new Duramax, but I’d rather me do it than some installer.

You really don’t have any overhead for a 7000 pound trailer, your GC will be maxed out unless you travel light with only a couple of people. I say try it for a while and see how it does for you. If you think it handles the weight OK but could use more grunt, for around $2K you can change both ring and pinions to a lower ratio (bigger number) to get lots more more torque. What axle ratio does it have? Some V8 GCs come with 3.07 ratio which is VERY bad for towing. My Land Cruiser has almost identical power as your trucklet but a 3.9 ratio, so it does OK. I run oversized 33” tires so I may actually change them to 4.33 to get back the lost power from that alteration. If you want to find out your your axle info, give your dealer the VIN and he can give you a printout. Unfortunately light duty SUVs have ratios designed to maximize empty cruising mpgs, which is bad for towing performance. There isn’t anything you can do if you need to carry more weight, except upgrade to a bigger vehicle. http://www.rvforum.net/SMF_forum/index.php?topic=104043.0 BTW your GC would be a perfect fit for the smaller Ollie.
