You should be fine without 4A IMO.
Since you don't have experience with RWD or normal 4H, you will just need some practice in snow to get used to it. I have had many rwd 4H vehicles and never used dedicated snow tires.
Wondering if there are any progressive lower end coil-overs. I am looking for a small lift 1.5 to 2 inch.
I see Bilstein usually defined as digressive.
I have not seen Eibachs listed as either progressive or digressive.
Are SAS take-offs digressive?
I think high end Fox, etc are...
IMO you need to live with it. I would not trust a dealer to make that better. It is hard to blend and match silver paint.
There are people who could do a great job fixing that- do they work at your dealer?- probably not.
When I first looked at this photo I thought it was on the floor and it looks 6 ft tall!
Do you know if there are any differences in the jacks listed from Tacoma, Tundra, Sequoia- or are they all the same height?
