Howdy - looking for any practical little advice on a long distance tow adventure.

Moving from Western Montana to New England, I'll have the OEM tow hitch quick release hitch and will be pulling the "medium" sized 5'x8' Uhaul trailer (trailer specs listed at bottom).

I've had the rig for about 2.5 years now and drove it home to MT from PA a few springs ago, I have the Gap IID, got around 112k miles on her, replaced the air compressor just a few months ago, and while I am handy on some things I also am not a full fledged mechanic. With that in mind...
...any pro tips or general good things to know/check for while towing in the LR3?

I'll likely be getting a coolant flush, checking (and replacing if necessary) my brakes, and doing a pre-trip oil change since my 5k miles would hit mid-journey.

Tripwise - I'll have 3 mountain passes until I get through Livingston and over to Billings, but from there it's basically flat for 1600 miles or more. I'm planning 6 days from start to finish to be conservative, but sometimes you get on the road and just keep going because you get in the zone (I've made 3/4 of this drive like six times in the last decade) - so if things are feeling good, I might have a day or two where I drive 12hrs or more. Hell I drove this specific LR3 2,000 miles from Pittsburgh to Western Montana in 2.5 days because she purred along so well (not towing though) just a little over 2 years ago.

Loose itinerary:
Day 1 - Billings, MT (5h8m - 343mi) (@55mph = 6.2hrs)
Day 2 - Chamberlain, SD (8hr - 523mi) (@55mph = 9.5hrs
Day 3 - Des Moines, IA (6hr - 420mi) (@55mph = 7.6hrs)
Day 4 - Indianapolis, IN (7hr - 456) (@55mph = 8.3hrs
Day 5 - Pittsburgh, PA (7h - 408mi) (@55mph = 7.5hrs)
Day 6 - Newark, NJ (6h - 355mi) (@55mph = 6.5hrs)


Uhaul Trailer specs:

• Volume: up to 208 cu. ft.
• Empty weight: 900 lbs.
• Max load: 1,800 lbs.
• Max combined weight of trailer plus load: 2,700 lbs.
• Max recommended speed is 55 MPH.
• Must have 1 7/8" or 2" hitch ball (2,000 lbs. minimum).

 

You wont even know it's there, other than the drop in gas mileage. I tow a 14' enclosed trailer fairly regularly - at its heaviest once picking up a car and total weight about 90% of the LR3's max capacity. I did know that was there, but it wasn't uncomfortable at reasonable speeds (65 or less). I wouldnt consider that without good brakes on the trailer, though.

 

Yeah that seems to be consensus, love to hear reinforcement on this.


Sidenote: The OEM quick release hitch is so expensive that I had been dismissing it and thinking I might some day just eventually do a cheaper one but, needing to button up no less than 1 million things before I hit the road, I just pulled the trigger and bought one after watching some YouTube videos on how it works - it seems both stupid to have to do (why not just put it in the bumper!?) but also a pretty awesome design with how easy it is to deploy and then remove .
