Each person has different viewing preferences, so the largest size might work for some viewers while that size may cause headaches or viewing problems for others. So, with that in mind, get the size that is comfortable for your viewing preferences and that fits the space.

Something to consider, especially if you do much dry camping, is that the larger the TV, the more battery power it will consume, so if you're going to be using it somewhere without shore power, consider the smallest size that will allow you to "efficiently" use the TV without consuming large amounts of limited battery power.

I suppose what I'm suggesting is that you tailor the size of the TV to fit your specific preferences and viewing requirements.
