Great suggestions on this site, thank you all.
I am really not complaining, we love this RV.
Just discussing our findings, all are minor.
I have found that if I pull the mattress down and away from the headboard it is much lighter, it was just getting bunched up there. It will still not stay up by itself but I cut a couple broomsticks to use as proprods. I can live with this.
There is no electrical junction box under the slide, though all other Rushmore's I looked at has them, seems they put mine inside the frame inside the underbelly.
Great suggestions on a table, I will find one as several of you have given me good direction.
I did buy a 4 pack of carpeted roller cups at walmart for $3. I can live with this also.
Reply: The rollaway island is covered and sits between the table and couch, I do lock the wheels to keep it from rolling on a turn,2 of thechairs are folding chairs stored under the bed to allow room for the island during travel.
I did have one more issue come up, the couch slide gouged into the linoleum in the kitchen area, probably an adjustment issue with the runners / rollers whichever it has.
Still nothing major, all will be fixed under warranty prior to winter storage.
