Congratulations on deciding to buy a van and outfit it for your photography adventures. I think that this is a great way to travel with gear, sleep and rest on the fly, and know that you've got the flexibility to camp or motel it on a whim.
I traveled with an R-Pod tow trailer for about 8 years and loved having a camper that could be towed by a Jeep Grand Cherokee. This served as a perfect way to park a camper for days and shoot a national park or BLM land. I, however, do not enjoy setting up camp and breaking it down. Furthermore, if you are between locations and decide to shoot while having trailer attached to your vehicle, it is a real struggle to park or move around. After years of working with a trailer, I sold my rig in 2022.
Fast forward to today,.. and I decided to jump back into the camper world with a camper van. I could not bring myself to spend the money on a sprinter, and I wanted something smaller and easier to park anywhere. While they are old and expensive to repair, I decided to buy a 2002 Eurovan with the Winnebago treatment. My van is currently being restored to factory production levels and comes with a 12 month /12,000 mile warranty. I've decided to add rooftop solar and a transmission cooler to keep it running smooth. While this is not a "cheap" way in, it is a little more than half of what I could find in a Sprinter that is outfitted similarly.
I think you're making a great decision and wish you well once you get to hit the road... Here's to running into other camping/vanning/trailering photographers in 2025!
