We have fulltimed in a 40+' toy hauler for over 4 years. with 9 to 11 of our 12 kids. We utilize the 'garage' as 'the boys' room' and hubby built custom bunks back there for them.
There are def benes to toy haulers and also to bunkhouses. If I did not need a toy hauler for the space to sleep kids, I would have a bunkhouse - ths are heavy, if you don't use the ramp, it's rather a waste and drafty, the garage is not well insulated, and it isn't at all 'homey'. But, with large dogs, it may be the way to go. With a bunkhouse, they are usually thousands of pounds lighter, and are already insulated and carpeted. That being said, I do love our toy hauler (not that I would buy a Gulf Stream again tho!).
We have done a lot of mods to ours to make it work:
