Here's what the inside of my camper looks like, with very minor changes because this photo is a couple of years old.

That looks nice!

Blowing sand and rain have not been a problem, even in 60+ mph winds. As long as I remember to close the windows...

I went for a long time just throwing a couple of duffel bags of stuff in the bed, but during the first year of the pandemic I built out the cabinets. I love them, but it does limit the amount of stuff I can haul when not camping. If I can find photos I'll send some.

A few of things to consider, totally personal preference:
The stand-up height and the window sizes are larger in the wedge camper, and having your head at the high end of the wedge when sleeping makes it feel a bit more spacious. I also like that I can "tune" my wake-up time by pointing the wedge to the east in summer so I'm in the shade of the top in the morning, or like now when it's cold I point the truck the other way so the morning sun warms things up. But I do see that the Tune would have better cross-ventilation with windows on all side. As I said, personal preference.

It's hard to tell from the gallery on the web site, but I've found that having windows with screens on the sides of the camper make it a lot more pleasant in bug territory. Having the sides folded up during the day means having to swat a bunch of bugs before you can sleep. I feel that several of the camper makers don't quite get that. Windows also make it a more pleasant place to sit in bad weather.

Be careful what you ask for -- you may not be able to get me to shut up...

This is a Vagabond Drifter (https://vagabondoutdoors.com/product/the-drifter/) and I'm super, super happy with it. I have (checks records) spent 700 nights in it as of last night.

Pros: not too heavy for a Tacoma, although I did add an extra leaf spring to the rear and upgraded the shocks. Very solid, almost trouble free. Big windows, lots of light, lots of cross ventilation.

Cons: If you carry a lot of stuff on the roof it can be hard to raise. I have a 200W solar panel, a set of maxtrax, and a Starlink dish up there, and had to upgrade the gas springs on either side of the roof. After the upgrade it works pretty well. Also, I sleep really well in it and I'm 5'10". I think if you were much over 6' the mattress might be a little short.

Depending: This is just a cap, what you do with the bed of the truck is up to you. I built mine out with varnished wooden cabinets and a place to sit and read. Lots of folks leave the truck bed unfinished so they can just throw gear in. Today was high, gusty winds with blowing sand and I was happy to be inside with a comfortable seat.

If that brings to mind additional questions, feel free to ask!
