We full-timed for three years with two boys and a 50 pound dog. I will advise you on what we found worked for us, perhaps it can better prepare you for your journey.
I would only consider a toy hauler, a bunkhouse would be my second choice. Toy haulers are unbeatable when it came to packing up large items quickly such as bikes, outdoor furniture, and other things full timers with kids accumulate. I would want a trailer in the 40 to 43 foot range. Triple axle, with at least 3 to 4000 pounds of cargo carrying capacity.
A bath and a half would be fantastic, I don’t know that we would’ve needed 2 showers with only one hot water heater. Which brings up my next item, at least a 10 gallon water heater.
With two bathrooms I would also like to mention that I would definitely prefer a single sewer outlet.
I would want a East/West bed in a slide out, with the large front closet for full-time use.
I would opt for no dinette. Maximum seating with the TV in a great position to watch.
I would prefer the washer/dryer be somewhere other than the master bedroom. We were running clothes constantly at night and I preferred to not listen to the machine when I sleep.
We live in Florida, so for full-time a residential fridge would be ideal. In the summer there is no RV freezer that will keep ice cream cold enough for our taste. The ice maker is also a blessing.
You can modify the top bunk on a Happijac to (2) twin beds in a North/South configuration. Just build a new longer deck. Ependydad on the Forest River forum did the same thing. Alternatively, one can sleep in the loft. The important thing is to have designated sleeping spaces that do not need to be taken apart and put together on a daily basis. The toy hauler allowed us to put 2 dressers in the garage for the boys to keep their clothes in. This was actually a huge feature for us.
Good luck on your search and I hope one or two of our suggestions might be of help.
