I may have some perspective....
We had a small 4x4 camper van for years. Loved it. Went anywhere, was reasonably comfortable, and served our needs well. As prices for it went through the roof (Wesfalia Syncro) we decided to sell while the market was hot. I agonized over what to replace it with...small RV....Sportsmobile....new 4x4 Sprinter, etc. We wanted to be able to go most places the van went but have more room and comfort.
Our solution was an older Lance camper. Paid $4500 for it. Everything works and it is COMFORTABLE. Queen bed, stove, oven, running hot water, bathroom with shower, tons of storage, 3 way fridge etc. There is absolutely NO way I could have built anything even close to it for 10 times the price. The appliances alone are worth more than I paid. I added 200w of solar and we can now camp for probably a month or more as long as we have water. There are 2 7gal propane tanks and I’ve never even hit the 2nd one. We run hot water, stove, fridge, and sometimes the heater for weeks and still on first tank.
I converted all lighting to LED for around $100 and the batteries/solar will sustain us forever.
We bought a 2002 F350 to carry it and it works well. Just got back from a remote spot on the pacific coast of Baja that is about 40mi of the pavement. Truck hauled it in and out without drama and we lived like kings.
I did do some work to the truck but all in my upgrades were probably only about $1000 if you don’t count wheels/tires. (I had to upgrade those based on what the PO had on it at purchase)
Overall, for the price we LOVE it.
Here’s what’s not ideal about it.
No tight tree lined trails. It’s 8ft wide.
No extreme rock crawling. Probably can’t make the Rubicon

. We have had it on some pretty bad stuff. Just put it in low and go slow.
Will not fit in a shipping container for transport. It’s just too wide/tall.
It is not a Fast/Light assault rig.
Lots of systems to maintain, but not any different than an RV or similar.
Have to store it somewhere.
What is great about it.
You can drop it off the truck and rally around empty. Super versatile.
Truck is useable at home as a regular vehicle.
Get a new truck? No prob. Keep the camper.

Did I mention comfortable? 2 surf buddies and I just did 10 days in Baja and lived large. Wife and I did a 2 week Oregon coast trip and lived large.
No additional registration or plate needed (at least in CA)
With a little shopping around Truck Campers can be had for pretty cheap.
Hope that helps.
