I would think it would be simpler in a class A as it pertains to preparation, set-up, and takedown, at least that's why some state they chose this class of RV. Most will say traveling by this class of RV is less stressful as well.
Since our TT is a second home it has everything we need onboard, it is always plugged in when stored in our side yard at home, and fridge is left on during the active RVing months to simplify the process that much more.
Since our 3/4 ton Chevy gasser tow vehicle is dedicated to pulling our 10K# 33' TT wherever we plan to go, it is always packed with firewood and all the other RVing necessities, which are protected by a rolling metal bed cover.
We don't have a list we follow per say, it has become second nature as most of the packing is already done. We leave freshwater tanks filled and batteries are always fully charged and ready to go, just hitch up and away we go.
Although we are approaching 60' when hitched up, we have a very comfortable towing experience. We primarily travel on interstates to get most places here in the West, my DW doesn't mind doing a couple of hours here or there.
RVing is not for everyone, main reason why there are so many slightly used RVs on the market. Next door neighbor has a nice fifth wheel and a newer diesel powered truck to easily haul it around, even so it hasn't been used in years.
Our other next door neighbor went though every class of RV before settling on a class A rig, they are in their 70s and they still go out often. They stated having a class A is the only way they are able to enjoy RVing, just jump in and go.
