No trouble at all if (again) you do it the right way. Many other Frontier owners have done levelling or more successfully before you with zero trouble down the road. I personally have a more involved lift on my daily driven truck but it's been solid and trouble-free for over 7 years now.
The truth of the matter is that the cheaper lift kits are cheap for a reason - they are the cheapest way to get the lifted look; however that's only good if you're truck stands still and you never drive it. Once you start driving it (especially daily driving) that is when common "cheap lift" issues like incorrect alignment, coil-bucket contact, axle wrap, and so forth come to light.
The wrong way is to slap on a spacer lift and call it a day. The right way is to install the spacer lift and (at minimum) have camber bolts installed as well in order to have the ability to correct the alignment after the lift. Unfortunately, since you mentioned that your particular vehicle does not come with OEM camber bolts, there's no way around it - you will have to spend at least $30-$60 more to buy camber bolts as part of the lifting process if you want to do it the right way.
^^ This. I have the camber bolts and All Dogs Offroad's upper control arms, with Bilstein 6112 front coil-overs and a 2" top-hat lift. The truck rides and tracks very well ( for a truck that is, don't ever expect this is gonna be a Corvette in the corners or a Lexus on rough asphault ( which is about all we get here in Maryland )), the correct way is never gonna be inexpensive, but it's the right way and will last, as Raine pointed out.
I just lifted mine last year but plenty on here have been lifted for over a decade. Do it the right way and it'll outlast the truck ( with the exception of shocks, which will always be a wear item, no matter what ).
BRW I got ARB / Old Man Emu shocks for the rear to replace my completely toasted stock Bilstein 4600s at 109k, and they ride great. Firm without being overly jouncy or stiff.
That Updated Suspension sticky is pure goldmine, read it and use it, it's free advice from those who have gone before, and I read it all the way through and took notes, before spending a single dime on suspension parts.
