Like you the RTT and even our KK mattress was just too darn hard/firm for us. For our then Overland RTT, our then Maggiolina RTT and now our Kimberley Kamper we had a local mattress manufacturer (small two man shop), Reno Mattress, make us mattresses that were/are worth it to us. No regrets.
Before moving on to a custom mattress we tried memory foam but its best if temps are above about 65*F. We tried one in the Overland the weekend we happened to be at Coyote Flats, SW of Bishop CA, when the temps dropped into the upper teens; it turned literally brick hard. Let's just say we didn't do that again
For the trips when its just me, my dog Sieg and the Land Cruiser without KK in tow, I use an Exped DAM 9 (Down Air Mattress) and its da bomb. Plush, quick to inflate (especially with my OBA) and compact when its travel time.
Oh yeah...five ten and two bills.
