Will it hurt to lift the rear but not the front?

I bought the Old Man Emu Suspension OMETUN57HKS with the 2613 front Springs and the D28XL extra Leaf. The problem is My Bumper with Winch will not be Ready before I leave for a 3 week camping trip from Arizona to Minnesota and back I will be towing a 5000 lbs. GVWR camper approximately 4500 miles all said and done. ARB says do not install the 2613 Coil overs with out the extra 200+ lbs of front bumper/winch weight. I wondering if I should install the rear springs before I leave for the trip. My thinking is it will help with the weight of the Camper plus gear in the bed, and would probably ride level. Problem is the Camper will not be hooked to truck during some sight seeing. At that point I suspect my headlights will be shining on the ground. I have no idea what it will look like. Also I don't think it will hurt anything? Trucks back in the day came factory with a rake. What do you guys think add the rear or go like it is. I also bought a set of Timbren Rear Active Off-Road Bumpstops, I guess I could at least add those?

 

I would go ahead and install the coil-overs. It may ride a bit stiff but I can’t see it hurting anything.

 

OME springs run a bit high, so your current 2 inch rake would probably grow to 4+. I think I would wait and do the rear when you can get it all done. Otherwise you could be looking like a late 60s musclecar with air shocks on the rear!

 

That isn't an option, if it was only a couple hundred miles maybe. I'm afraid it will fill like it felt when the pioneers settled the west in covered wagons for 4k+ miles

 

That is what I'm afraid of wish someone had a picture of just the rear being done.

 

Fair enough, I was thinking that with my fat ass and other passengers, the weight would be about the same as it would with the bumper/winch mounted.
