Motivation for buying the trailer...

What does the virus have to do with the trailer?
PS: Does anybody have a suggestion regarding making the tow/haul mode the default mode?...
I guess that's why my snowmobile dealer is still there..........luckily since I ordered one in the spring.Trailer sales are up substantially because RVing is one of the few outdoor leisure activities one can do safely.
Check out my new post on this string. My recent towing experience does not jive with yours...You are of course using tow/haul? Maybe something else is causing your overheat issue?I have a 2017 Expy and like many others was told it had the HD towing package which it does not. I added the trans cooler and factory brake control but since I tow in the mountains have had several instances where the temp still gets too hot. Ford will only tell me that I have the standard cooling radiator CL3Z-8005 A. Has anyone swap the standard out for the HD CL3Z-8005-B? And was id a direct swap or were other parts needed?
OK, some real world experience to add to the ragging conversation regarding Ford's mysterious HD radiators for 3.5 Ecoboosts...As noted elsewhere in these forums, I have a almost totally stock 2015 Expy XLT...The only upgrades are a Ford auxiliary trans oil cooler, 7 way tow plug and aftermarket EBC. Because of the stupid virus, wife and I bought a 25' trailer which weights in at about the 6,000 GVW level. Since March 2020, we have made 8 trips, just completing the last portion of the longest of those trips at about 6,000 miles, traveling from the PNW across northern states, down to Texas, west across southern states, up through Arizona and now in northern Nevada...Through the south the temps have been in the 100 degree range. Engine/transmission overheating results are: engine temp never off dead center normal, transmission never above 208 degrees (except for one time after refueling when I forgot to engage tow/haul)!
So, I truly still do not know if Ford makes a HD radiator for the Expy Ecoboost, but I ask the simple question: If the huge amount of testing that goes into a vehicle shows that "one" radiator functions under all service conditions, why would they make a "regular service unit" when there is little actual cost difference?

The entire front fascia of the truck unbolts in about 45 minutes, allowing full access for the auxiliary trans cooler area. You will also need the Lisle cooler line disconnect tool. You will find the trailer power lead capped off and buried in the wire loom under the brake master cylinder/booster. Search the forum, the answers are there...Take it slow, not a big or complicated job...Good luck...
Are you checking your trans temps?...The one time I watched my trans temps raise to a concerning point is when I neglected to engage Tow/Haul after refueling...Otherwise absolutely no temps over 208 degrees on 100 degree days, over long steep grades...I rarely use Tow/Haul on my '17 and it didn't exist on my '07. 6000 pound trailer at most. I do use it in what passes for mountains here on the east coast but only if I remember which is usually on downgrades where the added engine/transmission braking is very handy towing -- and not towing. Coming down the steep grade at Grand Father Mountain in western North Carolina Tow/Haul kept the truck's speeds in check.
