Laser printer/scanner recommendation?

Hi, I would like to add a color laser printer/scanner/copier to my pickup camper. Looking for recommendations/experiences on what to get or what not to get. Sometimes I have to do work from the road that involves printing and scanning. Quality scans of documents are important for my business, I can't use my cell phone for that.

Since I am in a pickup camper, compactness is important. Up to a 16" x 18" footprint would be preferred, smaller being better.

Rugged enough to survive the rough roads.

Is there something that I can print wirelessly directly from my laptop PC, or do I need to buy and set up some type of network equipment?

I want laser because my ink jet kept drying up from lack of use. Separate color and b&w cartridges would be a plus.

A (reliable) document feeder would be a big plus.

I used to have an HP inkjet that was constantly doing popups and was trying to sell me stuff. The HP software was like a virus that I couldn't get rid of, and was consuming my computers resources in the background, slowing it down. I don't want anything annoying like that.

I want something that does not connect to the cloud or the web unless I tell it to, and will function completely off line.

When I have to interrupt my vacations for work, I like to jump in, do it, jump out. No time for fiddling for hours with unreliable software/connectivity snafu's.

I have a 2000 watt pure sine wave inverter for power.

I'm hoping to stay under $600ish.

What do you recommend?

Thanks, Joel
