2003, we converted a 1996 Ford CF8000 commercial truck to our concept of an ExpeditionVehicle.
.
Windows:
We use 3010 (three feet wide by a foot tall) dual-pane sliders designed for a stand-still house.
We mounted these at our eye-level standing inside, about eight feet above pavement.
.
For the sealer/adhesive, we used Vulcum 116.
Nearly two decades full-time live-aboard.
Twenty-four months twenty-four thousand miles around South America.
Alaska, Panama, all over North and Central America.
.
The Vulcum 116 remains soft and pliable.

re -- silicone chalk
Semi-retired welder-fabricator here.
The squeeze-tube stuff you use around the tub in a stand-still house would be my NEVER choice.
.
Based on a half-century of camping in lesser rigs, experimenting with all kinds of combinations of components and chemicals, silicone chalk has zero-zero-zero stretch.
On a vehicle with each component constantly shifting, silicone chalk breaks, then requires a second application, then a fifteenth.
.
After a wet night with leaks everyplace, the silicone chalk must be removed so something appropriate can be applied.
.
Although silicone chalk fails at its primary mission of bridging gaps, it manages to adhere admirably.
To remove:
* you start with a putty-knife,
* quickly graduate to a chisel,
* by the third week -- family long-gone and the neighbors concerned for your mental health -- you are considering the nuclear option.
Trust me on this.
