Hi and Welcome
You can search for my posts for "newbies" - i pretty much offer my same ( narrow) opinion to new buys or "B-Curious"
There are brands other than roadtrek
The B is probably the most expensive cubic ft RV you can find, and each version is a pile of compromises.
It is important to define your priorities and the factors which you don;t care about ( for us, big bed fore and aft, don;t need 3rd or 4th seats )
Energy use and generation is a real factor if you want to be off the grid for days at a time.
older like mine use propane for stove, water heater and fridge ( also ac/dc), a genny for ac power air con and microwave, and 12 volt dc batteries for tv and lights
There are all kinds of "new tech" which are common subject of discussion here
we looked at many RV's and found in the end a perfect match and have a number of 3 & 4 week trips
The B advantage is mpg, ease of driving and parking
For a rapid run across country, walmarts are an easy overnight stop to rest and then hit road in the morning
We did rent- in Ireland, and the camper van appealed to us- at an age where getting out of a tent at 5am to pee was just not appealing anymore
