It's a good idea to inspect any Lippert frame for cracks and bad welds. Mine failed on my 2010 Keystone Cougar in 2010 - fourth trip out. Dropped the 5er onto my truck bed while going down the highway.
Had a 2010 Cougar 322QBS 5er, it was junk
01 Dodge 2500 4x4 360 Gas 4.10 Auto
02 Dodge 2500 4x4 5.9L CTD 3.55 Auto
07 Dodge 3500 4x4 SRW Mega 5.9L CTD 3.73 Auto
14 Ram 2500 4x4 Crew 6.4L Hemi 4.10 Auto All above are sold Tenting it and shopping for a Tacoma TRD
Everyone should inspect their frames. Especially if it is Lippert. I have some nice photos I would love to share of my Lippert frame failure. The inspection is quite easy and will take very little time.
