bone stock on the f350 but had bags and ranchos on the f250.
i might put some stable loads or something similar on the dually its squats the rear suspension just a tad below level but not bad.
btw those weights were on a 99 F250 SRW,STD CAB, LB not sure how much more my dually weighs need to scale it.
hey if your serious about this camper shoot me a pm. the have a week anchor/tie down system on them mine failed due to water damage and weak materials. i think they are still awewome campers and the problems can be fixxed fairly easy.
