I had same problem with my "RV King". It was ok for us; but the dog kept rolling off the bottom of the bed because there was no support. I have a 4 inch foam topper on mine(highly recommended); so I just slide a 3-4 foot piece of plywood under the mattress and it worked fine. You could also screw it down or clamp it with construction adhesive. As far as ruining your mattress; if it is an original RV mattress; they are junk anyways ; so I would not worry too much about ruining it.

Before I put the foam topper on mine it was HORRIBLE, no sleep, back aches, etc. Now I sleep better in the RV than at home on my expensive king sized foam mattress.

I ordered mine from Kohl's on-line. It was on sale and I had a 30% discount coupon; so it was very reasonable.

We bought a 10 inch memory foam mattress from Aldi grocery store for $189 queen size to replace RRV queen mattress luckily for us ours was a full size queen so it did not hang over.

Our Flagstaff 829FKSS is a bit short also, But that is a good thing. The plywood on our HR Savoy came to the end of the mattress and the point stuck out a bit. Said ouch and a few other choice words several times.

I've tried to pull the platform out, but it's attached via hinges near the head (not sure why, the storage area underneath is not accessible when lifted). Am I missing something here? I know I can add a simple plywood extension myself, but why would FR manufacture a bed that's shorter than the mattress?

We have the same Coach and we have the same issue (mattress hangs over). We did buy it new and upgraded the mattress to a Serta pillow top. Yes, it is a RV mattress and is about 5 inches shorter than a standard mattress.

We've talked about sliding a long piece of plywood under the mattress to make up the difference. Figuring the weight of the mattress should hold it in place.

Will experiment when we get her out of storage.

We added a piece of plywood to our bed and topped it with 2 regular twin size mattresses, making a somewhat short king size bed. We happened to have 2 spare twins in decent shape so gave it a try, and have been very pleased. The biggest drawback has been giving up the walk-around space, but a small price to pay.

Ours is a short queen & we thought about a longer one & adding support but our bed is on a slide in and the extra length plywood would be into our cabinets with the slide closed. Not a problem for us....but worth checking if you're gonna add to the original base plywood which may have held a shorter queen IF you are on a slide as well.

My 2015 Georgetown 328ts have the same issue the plywood is not as long as the mattress from the factory, my bed hangs over the ends about 4 to 5 inches. I figure that is to allow the slide to be able to close all the way.

Darren, I had the same problem on our Georgetown 370xl. Our 2 bedroom slides face each other and when closed limited our mattress length. My solution was to go to Lowes and purchase a 4' tall shelving unit with chrome legs that is 12" deep. The 4 leg sections screw together so I assembled as 2 separate sections about 17" tall which is approximately the bed platform height.

When the slides are opened, I put the the 2 sections side-by-side at the end of the bed, then pull the mattress down with about 6" laying on the shelves. The gap at the head of the bed is then filled with extra pillows to bring level with the mattress top, then add your sleeping pillows and you now have added 6" or more to your bed length. Store components and pillows under the bed when slides retracted.

..... sleeping much better now. Pleasant dreams.

I forgot to mention a huge plus with the shelves added at the foot of the bed to support the "pulled-down" mattress.... they make great racks for numerous pairs of shoes.
