I’ve been lookin and lookin and can’t find a thread to help me decide which to setup to get. My father n law has a 2015 2500 4x4 cclb dmax. Leveled, bone stock. Pulls a 38’ fifth wheel camper and it squats it a little. I’ve talked him into gettin air bags to help it. So what do y’all think from previous experiences? Which brand. Best warranty. Installation. Best all around etc. Thank y’all for any help. It’s all appreciated.
