OME 2811 backorder issue

I have put myself in quite a bind here and I'm hoping someone out here can lend some knowledge to help me out.
I have a trip coming up that is going to require a lift on my 2000 SR5. I cant really get around needing it.
I have been planning to put in the OME 881/890 springs with bilstein 5100s. No big... except the 881 springs are backordered 4-6 weeks. I could deal with 4 weeks but more than that and I'm screwed.

I am totally fine going with a different lift if it achieves the same height as the 881/890. I cant seem to find info on what the other options are (that aren't $1k+ just for the front)

Does anyone know what other springs/ setups are comparable to the OME 881s?
Suggestions?
(Im not panicking, you're panicking!)

 

I’ve got a new set in my storage unit if you’re in Colorado

 

Curious as to what trip would require a lift?

I did some Moab trails on a stock rig with no bumpers or sliders.

 

Hah, pretttty far from CO but I appreciate it nonetheless.
The trip isnt far but I'll be towing a 21' trailer and I am certain the old springs will not hold up to that kind of weight. Especially not through heavy sand.
