    Ignorance of the Laws of Physics may bite you

    I read posts all the time about structural failures that are blamed on “poor workmanship.” It could be the laws of physic at play. Namely ‘a mass in motion tends to stay in motion’ to paraphrase. Do you have a cabinet or drawer loaded with canned goods, you bar stock, all you small appliances, your grill and outdoor items, your winter clothes, tools, generator, or carry full tank of water in transit? Do you ever hit potholes, collapsed pavement, drop off fuel station aprons, or run up on curbs? Then you are lucky if you haven’t had a frame crack, cabinet bottom or back break, floor bulge, or slide out floor sag. Full timers especially take note with all your stuff onboard. That mass of stuff exerts far more downward force that just its weight. Spread it out. Disclaimer: I believe GD builds one of the better products and I don’t work for GD or a dealer.

    Rabbit Your spot on where impact loading can add mass by many factors to a structure through kinetic energy, but suspension and tires is also not a good place to save on cost and weight. There are far better suspension systems out there versus the Ben Hur systems that are commonly utilized. Once I added one inch lift blocks to my rig to prevent tire to floor contact, I have been successful in keeping my 3500lb axles and 1750lb springs in check on our 2017 2600RB. The Imagine line was upgraded in 2019 to 2200 lb springs and 4400 lb axles where design is a factor here as well.

    Aside from this we also believe the GD products are good.

      Yes, I'm a firm believer in "you make your own luck". We all know somebody that always has stuff happen to them...and if you watch that guy...you will probably see why.
      A little forethought can help keep your bad luck to a minimum.

      As for GD build quality, I agree they are better than most. We still go to RV shows spring and fall (with no real intention of buying) and look at all different brands. In recent years I have not seen an RV brand that I thought was better built than GD. BUT.....I don't think I've seen a 5th wheel that I thought was well built.

        YEP - Over the years I have learned a lot. On my Alaska trip I had drawers fail with even fairly light stuff - GD use light partial board a reinforcement on the drawer structure. I put heavy can goods under the bed - not in the pantry and only put light stuff like paper good and pot and pans, even then I needing to add reinforcement to the bottom of the shelves. Yep gravity will teach you lessons.
