Sleeping platform

I've had my 2nd tacoma for a little over a month now and can't stop thinking of mods that I can't afford! One thing I can afford though is some wood and carpet to make a sleeping platform because I love to camp! So i have a few questions; 1) I have a Leer camper shell and is it possible to easily take the cross members out if I need to? 2) is it really that uncomfortable to sleep in? Even with some thick memory foam pads? And 3) share pics of your sleeping platform if you have any!

 

I get an air mattress and throw a little mattress pad on top, it's pretty damn comfy.

 

What size bed and mattress?

 

[ two month trip around the states and canada a few years ago. 2/3 camping, 1/3 motel 6. used a Napier Sportz tent for longer stays like the grand canyon or Yellowstone.

a Leer 180 for a bit extra headroom
platform materials cost about 125 from Home depot

 

That looks sweet! I want to travel the U.S one day haha

 

I have a long bed and The mattress is a twin size. Pretty decent fitment.

 

I’m aware this is a dead thread, but thought it would be good to put this out there:
This sleeping pad fits perfectly within the wheel wells in a long bed, and you can still close the tailgate! The exped duo medium, either the “megamat” or the “deepsleep”
