Traveling across the country in a Hybrid???

We moved from a pop up (20 years) to an ultralight trailer (now 13 years old). We started to find the pop up damp since there was no insulaton. We have towed our hard side trailer all over North America. It is nice to simply pull in and step in the door without having to open trailer beds. In cold, damp weather, (Alaska) we found the hard side fantastic- simply put on the furnace and warm in minutes. It really comes down to lifestyle and expectations- we wanted less dampness, convenience of set up, warmth, etc. We are unusual in that we ordered ours without an AC since we seldom toured in the extreme heat seasons of the US southwest or Florida- never needed it in Florida in March. Heading south in February is a cold trip until past Kentucky- we have slept in ours at -13 degrees C and no problem- that creates a problem with a hybrid unless the ends are kept shut. Hybrids give more of a camping experience. Good luck and happy touring. We have enjoyed our 21 foot since we can go places the large units can't but have to live with a smaller space inside.
