Is anyone having problems keeping shocks on their rig other than me? I have run through OEM, Rancho's, & Monroe's. I have a slide in on the truck permanently. I see others who have heavier campers than mine and don't seen to have any problems. My truck and camper wt 11800, 4540 frnt and 7180 rear. Front axle is 40lbs over, rear is 320 under GAWR. Truck has camper pkg. Shocks last abt 3 mos tops and then go soft and truck rides like no shocks.
