Smart man to install HD new springs. One of the first things I did when I got my 2019 F350 SRW truck. I took mine to a specialty off road shop ( North County Spring ) to have them swapped out. Cost a little under 2k for the install. Loaded up the camper and dropped it off in the morning and picked it up at the end of the day. Progressive 7 leaf pack is what I got. Truck sits level with camper on and I also have airlift bags that I put about 45lbs in when going off road to smooth out the bumps a bit. The airbags don't actually lift anything they just firm it up.
