Attention: TDR Forum Junkies 
I read through the posts on the Snow Plow package and what springs came on what trucks. Mine were the 039/038 and I decided I wanted alittle more spring cappacity for when my slide-in is in.
So I bought a 046 spring for the drivers and moved the 039 to the passenger side. I forgot to measure ride height before so I cannot compare but I would say the heavier springs don't sag as much an I gained 1/2" to 1" as I wanted the rear to remain higher than the front.
Ride is firmer but not rough, perfect!! Took about an hour with air to swap out both sides. For anyone thinking about it, just do it!
