  • 2020 3950BH Unintentional Pet Access to Storage Bay

    We recently purchased a 2020 Solitude 3950BH and have been very happy overall, however we (by "we" I mean our cat) discovered that there was a pathway through the under-stair shoe compartment into the external opening storage bay. Sitting outside, and much to our surprise, out pops our cat from storage (he looked just as surprised as us, and we assume it would be like discovering the pathway to Narnia).

    I had to go into the storage area and take down the wall separating the storage area from the pluming and electrical area and board up the two holes with some plywood (each one about 15" x 20"). I'm not sure if the holes are there to allow air flow into the storage area, but it can present a problem with your smaller pets if your not aware.

    If the design was intentional and are critical to air flow, please let me know and I will drill some venting holes into the newly placed boards. Furthermore, if it is intentional, Grand Design may want to place Louvre vents there to allow airflow, but prevent passage.

    Hi Shane . . . Welcome to our owners technical forum!

    There is a good change that you are correct that this is the air return path for the furnace. You might need something like a "chicken wire" barrier to maintain original airflow back to the furnace.

    I will tag GDRV-Megan at Grand Design to confirm that this is an air return and to get your suggestion(which I agree with), to the Solitude design group for a "cat proof" screen in this area. (Our cat Gracie would love to wander around down there!)

      This is interesting!! I'll get the scoop and let you know!

        What I'm being told is that you may want to drill some holes into the board or your HVAC system may not function properly. Some sort of louvered vent or access is something we will need to consider though for future units. Thank you!

          Wire mesh would work well and wouldn't restrict airflow.

            Thank you all, I’ll go in and adjust what I did to allow air to move through there.

              We don't have the 3950BH, our RV is a '20 Solitude 385GK. However, the shoe storage area under the stairs sounds like what we have in the 385. This area is the return air route for the furnace. We have had a lot of problems with the furnace running on the hi-temp limit. With this condition the burner trips on hi internal temp, the fan continues to run to cool the unit off. If after time-out and the box is cooled, the burner will re-light. This condition existed from purchase. We took delivery of our 385 in August of '19, in Texas. In the Texas summer heat it was impossible to "test" the furnace on our PDI. Yes, it ran and blew plenty of hot air. As outside temps cooled in the fall/winter, I began to notice the furnace seemed way under capacity for the 385. When outside I began noticing the burner would shut off and relight. The cycling lost heat capacity/hr, meaning it would take a very long time (hours) to raise the inside temp just a few degrees with only moderately cold temps outside. This was very different than previous experience.

              Brought to the dealer for resolution of the issue. However, before bringing it in I did my research so as to not be fooled by the dealer. I had learned from talking with technical department of the furnace supplier details about the condition I was experiencing. Learned this was caused by 4 typical issues and the first 2 were air flow. The dealer had the Solitude for 8 weeks. Of course they started with the same usual response of changing every part they could, control board, temperature switch, igniter, only thing left was to change out the entire furnace. All this even after being explained what I had learned on the furnace operation from the supplier.

              Finally a breakthrough. The service department personnel attended a workshop put on by the furnace manufacturer. In the workshop they learned the issue being experienced was most likely due to air flow. So with communication directly with supplier they began chasing air flow. After a few threats, they also contacted Grand Design who also said to look at air flow. The fix proposed by both was to add some additional air duct outlets. While this seems to have helped it will be difficult to get a good performance test of the furnace as we are again enjoying our Texas summer heat. Yes, we enjoy 4 season camping, their just all the same, "Hot" and "not as HOT".

              Long story to say that blocking off the opening under the stairs will quite likely starve the furnace for air. At a minimum it will severely restrict the air flow through the coach, low air flow out means low air flow in. The furnace system in our Solitude appears extremely sensitive to air flow, Grand Design design issue. I have read about others experiencing similar issues. The suggestion to drill some holes will likely still result in significantly reduced return air flow. Minimum return air size is basically achieved in the Grand Design design, be careful of any modifications. Screen, mesh and even turns in the route reduce air flow. The furnace manufacturer refers to return air size as "straight flow".

              To resolve the issue of the escaping cat, you might look at how to block off the basement wall gaps. However, this would still allow access to the compartment behind that wall. And if you are aware what this looks like you would not want any pet down there.

                What a fantastic first post--welcome to the Technical Forum! I hope you'll continue to contribute (and ask questions when applicable).
