Sort of. we bought a 26' and if I find a Nash that's 29', I'll probably swap.
Part of it depends on how long you'll spend in it. If it's just for a 2 - 3 day weekend, small ones are fine. If you're going to do a couple of months in it, 25' is just a little too short in my opinion, especially if you get into some bad weather. You need an extra foot in the bedroom to get around the bed, and extra foot in the bathroom so you can turn around or towel off, and an extra foot in the kitchen so you have enough counter space to prepare a meal.
