Welcome to the gang Rod, enjoy here and out in the playground.
I have a 20ft aluminium teepee and have no problems. I did heaps of research etc prior to the order and purchase and very happy with my choice. I am solo and I went with single beds at the front to give me a more open look that end but have since done a change and have a bed east west now and it looks fine so give the bedding extra thought maybe.
Make sure you research all the weights and measures for the van and it ticks all your boxes. Make sure the van will carry everything you want and need and doesn't go over the ATM. Not all dealers tell you the truth and you could come into trouble down the track.
Keep Safe out there.
