we use bedding because the DW prefers that. i'd be fine with a sleeping bag.

we wash the bedding when we get home and then put it back in the hybrid. we furnish our hybrid as if it were a cottage.
the only thing we don't keep in it all the time, is food, some clothing/toiletries and outside stuff.

When it's warm out we use regular bedding.  When the temps start to drop we switch to sleeping bags. Our DS sleeps in his bag and the DW and I sleep with one unzipped bag below us and one over the top. If it gets real cold blankets are added as necessary. 

In the spring, summer and fall we use bedding.  The fitted sheet stays on the beds and the top sheet comes off when we pack up the camper.  We also pack sleeping bags in the camper in case of cold weather.  Then, depending on just how cold it is, we either use the sleeping bag as a comforter, or if it is really cold, we zip it up and get inside.  I prefer bedding because it allows freedom of movement...however, can't beat a sleeping bag (especially a mummy) for warmth.

2 large slleping bags zipped together for us

We use sleeping bags when it is cold but during the summer it is regular bedding

Yep, zipped together bag for us with a flat sheet inside. Separate bags & flat sheets for the boys.
And yes, the bunkbeds are always made up & ready btwn trips. We even have pillows that stay in the trailer. Our sleeping bag is folded w/ the sheet inside resting on one of the boys' beds. When setting up, I just pick up the whole thing & flip it open on the bunk or sofa, if we're turtling.

We use regular bedding. Take the sheets out and wash them after each trip and wash the comforter every 2 or 3 trips depending on how wet or dirty the trip is.

We use sheets and a sleeping bag unzipped if needed.  In cooler months we use a flat sleeping bag under us and  one top.  If it is really cold (under 45) we can turn on the furnace.
Happy Camping

The DW likes to use sheets and a blanket and I still like to use a sleeping bag.  Since we each use a bed it works just fine.  Charlie the dog :dog: doesn't seem to care and sleeps with either of us as he see's fit...

We use sheets and blankets. We were told, when we bought our teardrop, to sew the foot end of the sheets together so you don't have to tuck them in to anything. Feet stay covered even when they hang over the end of the bunk. It is also easier to make the bed.
