I think you will be plesently surprised just how well the Gen 4 Limited V6 does everything well as highway cruiser. The only negative might be the seating comfort. A pad, a blanket ,or a pillow, might be a good take along just in case. Have fun Gary. This is what your Avalon was made for.
I had a safe drive and a real blast. After my stops in Winnipeg I Left phone in ignore mode, popped my USB stick in and set it to Bob Seger's Greatest hits cranked the volume up and hit the TransCanada Wetbound. although the song "Roll me Away" says "I could go East, I'm could go West, it was all up to me to decide"... Going West was the smart direction at this time of year. Last thing I wanted was driving back with the sun right in my face. Wound up in Brandon MB. and needed a bladder drain big time and had some McJunk. Then headed back. Rear sun shade came in handy then half way back I got night time driving and really love the auto everything, (leveling headlights, high beams, auto darkening rear view and side view mirrors) but the best is definitely the auto darkening side view mirrors!
I checked my phone when I stopped in Brandon my rear end needed a break and saw your post and thought: Gee thanks for the seat tip after the fact
. LMAO Definitely no where near the gen 3 seats comfort but definitely better than a Rockin 'Rolla! it'd be OK if I hadn't lost so much weight these past years! my "natural bottom cushion" don't got much padding left! The Gumout Regane started improving my fuel consumption and fuel sender quirks. There's a couple Traffic lights where you slow to 80km/hr then back up to 110. and was lucky to get most of them red. I was in eco mode and i had fun a few times nailing a take off but full throttle acceleration is insane the front is not heavy enough and the rest were a mile back in no time even at way less than full throttle. Definitely has the acceleration when you need it or just want it. No stutter or hesitation whatsoever. Beautiful sunny day to boot over 50F.
P.S. Watch out for the POTHOLES. More so with the 18 inch wheels.
They're a rare thing here since there's only one freeze thaw cycle. Once the ground freezes up that's it till spring. The major highways have a concrete slab as a base probably a foot if not more thick with a little asphalt layer. BUT when they do the roads then take a concrete saw and literally cut expansion joints across the road about every 2nd doted line and fill them with some rubber sealer. When they are worn it's smooth but when they need to be redone or like yesterday have recently been redone they fill em up a bit higher so it's like riding 4 basketballs... tock a tock a tock. So no pothole slalom fun.
