    Rethinking Grand Design.

    Help me please! I recently put a deposit down on a Reflection 300rbts. Now I have found out that they use a styrofoam and luan floor in this Reflection! I thought only cheaper light weight trailers used that type of flooring! I have read, seen and heard of problems from that type of floor for years in RV's! It has me wondering if I need to cancel the buy on this trailer and go a different direction! The factory told me not to worry they had a 3 year structural warranty! But, I plan on keeping this trailer far longer than that! This was intended to be our last trailer until we stop camping, which I hope to be 15 to 20 years! Should I worry that this floor is only styrofoam and two layers of 1/8th luan? I am very knowledgeable about materials as I have been in construction and manufacturing all my life. This floor system scares me!

    I was unaware about that floor material. Have you called GD to confirm what the construction is? You could always switch to a Solitude or Momentum, I know mine (Momentum) is made of plywood for sure.

    Sounds like wall construction not floor construction. I would call GD to confirm.

    The GDRV website and brochure link communicates the use as PTParker describes for Reflection TTs and 150 series Reflection fivers. This said, I would call GDRV Customer Service 574 825 9679 and ask to talk with and learn more on current builds. It is certainly possible things may be different as with rolling changes, and if not, at least to learn more about this.

    There have not been many folks express concerns about this construction method nor having issues. Some squeaks and or flexing but we have this with the wood marine grade plywood (5/8" I think maybe 3/4" ?) floors and fiberglass insulation occasionally as well.

    Yes, I emailed them, they confirmed it is made of foam and Louan! Worse yet, it is made from louan instead of plywood! If you know about materials, louan is not even to be used as a structural material! It is a single ply soft wood made for hobbies and making toys! It breaks easy and swells easy from moisture! I am very close to canceling my order with Grand Design even if I lose my deposit! I am beginning to think they are selling pyrite for gold! The more I research, the more I am feeling that their quality is only skin deep! I have looked at other trailers that seem to use better materials everywhere, from suspension to floors to cabinets! The more questions I ask, the more I find I don't like!

    That is why I am asking. I have found literally hundreds of post about problems on almost all models using this type of floor! Some come from not enough supports in floor, some from water, and some from floor just being weaker from beginning! I have talked to a Grand Design rep that confirms that all Reflection travel trailers and 150 series fifthwheels have this type of floor!

    Nope, Rep confirmed the floor is made same as the walls! Or very similar. 1/8 louan on bottom then foam, then two layers of 1/8 louan on top!

    @PTParker - Good thing you called GDRV and they confirmed the construction for you. Certainly not what you wanted to hear as your concerns are shared quite clearly. Sounds like it would be best to consider a different product or manufacturer. Hopefully your dealer will work it out with you.

    I really like this layout, and I will fit in my building with removal of the ladder and a little modification of my building, but this floor concerns me! I have ask them some more questions about it and challenged them to convince me that theirs is better than all the other failed floors of this construction on the market. I guess I will see what they say before I make my final decision. I really wanted a Grand Design after all the good things said on this site about them, but I wanted this trailer for the long haul.
