Replacing Water Heater

Small trailer with 6 gallon hot water tank.

Am considering, prior to next season, replacing it with a 10 gallon.

Is the difference in size that significant, and has anyone done this sort of thing, who may provide advice or things to be aware of?

This does not seem like the type of query to "phone a friend" over.

Noone here would have the slightest clue whether a larger water heater would fit in you RV or exactly how much of a project it is to switch out.
But, I bet you could find the size of one on the internet in less time than it takes to write this post, and then go break out the tape measure.
