Tundra to Taco Need Help with Ground Clearance and Suspension

I have searched around a bunch and need some real world advice specific to my needs.

Old truck, 2006 1st gen Tundra. 12.1" ground clearance stock. 265/75/16 Load E and 1" spacer up front. Upgraded shocks to just some more quality shocks like kyb or rancho 5000 comparable. This was almost the perfect dd/offroad and "semi" work truck for me, it just wore out. Rode kinda stiff but I liked it and that thing was a beast anywhere.

I just got a new ACLB OR which supposedly has almost the same payload and towing capacity as the truck described above. However, it feels like a much weaker truck overall and way less capable offroad (thinner metal, way more plastic etc.) and only 9.2" ish ground clearance. I need to fix this while trying to maintain decent mpg.

I need to gain clearance at the front skid plate. Can any clearance be gained there via spacer or coilover lift relatively easily?

Some rake is ok and I need to be able to carry weight.
This is my first full day with truck, had to do some work but did keep it very tame during break in period.

Put a 600lb atv in bed. This was not very confidence inspiring. The whole truck was shaking about and the rear leafs bent in the other direction with a fair bit of squat, Can't really see it in this particular pic. This is at less than half of payload.

Don't like how the truck handles and it is way to low to the ground for me.

I will at all times have a topper and tools in the truck aprox: 350lbs not including me.
Live in the mountains at 10,000ft and the truck spends around half of its life on dirt roads and rougher terrain. I guess most important to me is in this order:
1-offroad ability
2-towing payload
3-highspeed highway
all without going under 17mpg

Potential fixes:

1. Since new gear, add a 1" thick spacer to front shocks for 2" +- "lift" dunno if this will raise the ground clearance at skid plate or not.
1-2 sizes taller tire, not wider
Rear progressive aal for lift and extra payload.
Use this till something wears out and save up a bit of cash for option 2.

2. Bilstein 6112 coilovers in front. 1.75-2" lift dunno if this will raise ground clearance at skid plate or not. Will this give me more travel?
1-2 sizes taller tire, not wider
Bilstein 5160 in rear, will this give more travel?
1-2 sizes taller tire, not wider
Full new leaf pack in back rated for 600lbs or more.

I would really appreciate your thoughts or suggestions.

Thanks!

 

Had the puck style spacers on my tacoma and it rode like a brick wouldn't recommend it, especially if you'll be wheeling. Coilovers from bilstein or eibach are a decent start.
