New GX and need to set up for towr

Just purchased a 2019 gx 460 with 56k miles with a plan to tow an Escape 19 or if my wife can handle a smaller trailer, a Casita 17. The plan is to spend next May in Alaska, driving from the SF Bay area.

Researching it, the nominal planisas follows

Update infotainment system with the Hamilton look alike box on Amazon. Already done and it works great

Eibach stage 2 lift kit. 1.75" nominal lift with adjustable front lift

OEM class 4 hitch. Looked at rear bumpers but they all have "recovery " hitches which apparently insurance doesn't cover if something goes wrong. Would like a better solution if you have suggestions. Need the full rated capacity 6500/600

Redarc brake controller

Anderson weight distribution hitch

Goliath tranny cooler bracket with Hayden cooler

Falken wildpeak AT4 265/65/18 which should fit in the standard spare location under the back

Of course, the usual fluid replacements and maintenance

Will look for a trailer with the high axel options and largest wheel options

Does this sound reasonable?

Will consider under armour if I get into more challenging off roads than the typical dirt roads to campsites and logging roads. For now the plan is to turn back at impasses
