Adding additional floor frame bracing? December 10, 2018, 02:33:05 am Yahoo Message Number: 16916anyone ever added additional floor frame bracing on these things? i swear my rig is developing a wall sag type situation that toy hauler trailers are notorious for. I'm noticing that the floor, especially in the center in the living room and the bathroom between the truck chassis frame rails, has started creaking loudly when walking around in the coach while parked and set up in numerous different areas of the coach that it has never done before. if I'm sitting outside at the campfire, i can tell exactly where the wife is walking in or moving inside the motorhome as the creaking sounds move around to different areas of the motorhome. have also been noticing some very strange and concerning creaking and cracking noises in the sidewalls while driving as the coach flexes and moves around depending on the road conditions. the floor framing is simply attached to the chassis frame rails in a 'T" looking type situation with no support from any sort of outriggers that would help to hold the outer part of the floor and walls up. i had a peek under my buddies 26' 2018 coachman freelander on the 4500 chevy van chassis and it has outriggers present. I'm strongly considering picking up a couple sticks of steel and going to town making and welding in outriggers wherever i can access to install.thoughts?
