Which would you choose and why?

[Ats666]

2014 sierra (sle I think?) z71 4x4 5.3l 6sp regular cab long bed, running boards. 

Maintenance is all up to date, needs nothing. Bought it 2 months ago. 

Diablo tuner otherwise stock. 

 

This is my work truck, tows an aluminum vnose enclosed 7x12 trailer. 

 

I'd like to either do 1.5" level up front or 1.5" body lift. 

Which would you choose and why? 

 

I've had suspension lifted trucks in the past but never one with a body lift. 

 

I'll likely add a cap on the bed with ladder rack and a rear air bag kit. 

 

Thanks
