Welcome to the road! Great decision y'all made! I am working on my 9th year, and have not looked back yet :)
Some of the best reading you can do for all of your trailer/5th wheel questions is on RV.net and IRV2.com forums. There is a ton of info there, and you will see trends on what people prefer.
As for talking to your employer, I recommend reading The 4 Hour Work Week. He lays out a great course of action to take in working with your employer to start working remote. The whole book is full of great ideas on how to make work more efficient and free up time to do fun stuff!
Good luck on getting everything together. Please feel free to ask any specific questions - we should be able to hook you up!
