Getting mixed information on mattress size...

[PaintballMomma]

I’m “buying” a 3124, the owner is telling me I absolutely have to have a 76” sq mattress of 4” thickness, which doesn’t seem to exist. So can I just buy the 6” foam king size mattress I found on Amazon or not? (I’ll also start reading/searching through the forum, but I’m new to that to so...)

I’m actually being gifted the RV sight unseen, but am told I need a mattress and tires immediately...so I’m bringing those with me from Illinois...RV is in Florida...

Thanks for any advice/help,
C

It is quite possible that a 6-inch thick mattress will be so thick that the rear shell won't close. That would be an expensive problem if you just bought a new 6-inch mattress. Presumably the bed already has a 4-inch mattress on it. If you are squeamish about sleeping on a "used" mattress, why not buy a zip-up waterproof mattress bag or cover? That way, when you take possession of the camper, you could measure and buy something that is guaranteed to fit later.

Great suggestion, I guess I didn’t make it clear that there’s currently no mattress in the RV. Otherwise, I would just cover it as suggested...

My main concern was the 76” square, that’s not the dimensions of a king mattress... and I can’t seem to even find a Trailmanor mattress for sale to see what its dimensions are...

I’m probably just not searching in the correct places...

RV mattresses rarely, if ever, match the standard sizes we are used to at home. In fact they aren’t even standard amongst the RV industry... I can tell you that for as long as I’ve followed TM, their king bed has always been listed as 78”x78”. And I can also tell you my mattress is 4” deep.

As for not closing, the general consensus has been you can put a 1.5”-2” Topper on the mattress and still close the camper. But I don’t know that I’d spend the big bucks on a 6” mattress. With a topper you can always roll it up and stash it if needed. Can’t really do that with a mattress. Another option that some have had success with is an air mattress and electric pump. If it’s too tall to close, just deflate it.

I figured the owner was off and did just find the picture that showed me the 78x78. The 6” mattress is only $189 on Amazon, so I think I’m going to chance it, but before I decide I’ll check out an air mattress, or maybe 2 twins side by side, or see if I can find a 5” mattress.

I found 4” twins, which side by side will fit and then there’d be a 3” gap, but I found cheap 4” twins. Gosh who knew the stupid mattress would be such a big deal...actually I’m probably in for a lot of surprises with this whole situation and being new to RVing. 😄

Wait a king mattress is 78”x80” isn’t it, so that doesn’t work...ahhh!

Good luck with the gift. I would assume it comes with some problems , because the need for a new mattress means that it got water damage or rodent infestation. The rotten state of the tires may mean it set outside for a long time. So you may be getting a wonderful deal, or something that it would take so long to fix that it's not worth it.

What year is the TM that you will receive? Do you know if it has been stored in a garage / under a carport / out in the open? How long since it was opened and used?

If the mattress you buy is a bit too big - say 78 inches vs a 76-inch "box", it might be difficult to stuff it down into the box that encloses it. If you are in this situation, you might be able to put an air mattress under it, to boost it up and let it lap over a bit. Note that I say "might", since I haven't done it.

On the other hand, if the mattress you buy is a bit too small (say 76 inches to go into a 78 inch box), it is easy to fill the gap along the edge. Many people do it with pool noodles, for example.

Paintball Momma, can you hold off buying a mattress till you get and see the camper? Is there any chance to get pictures of the camper?

The mattress can NOT be too thick, over 4" will prevent the back or front shell from closing. I replaced my back mattress with a foam futon mattress, it was too wide, but the store owner was able to cut it down to fit the bunk dimensions. It was also 2" too short, but that has not ever been a problem for me. I know I've read on this forum that folks have used an inflatable mattresses in their TM, so there are options. I would wait till I see the camper before buying any items for it.

The attached picture shows how little of room you'll have when you close and lock down the back camper shell, height size matters.
