Four folks in one of the FGTs is a challenge, but we opted to view it as an opportunity for all involved.
When we're not shoehorning our entire family of four into the full-size bed of the 13' Compact Jr., the husband and I sleep in the tent outside while our kids (now 6 & 9, but we first did this when they were 5 & 8) sleep in the trailer. They lock themselves in (we keep a key outside with us and they know how to unlock the door as well), then have a hayday in their own "room." We don't worry about bedtime (a TRUE treat for the kids), so they read, draw, talk 'til they decide it's time for lights
out. (Late the first night, but then they exhaust themselves and turn out the lights
earlier the next night.)
Gas - we turn off the propane
at the exterior tank so even if a knob gets "accidentally" turned, no one will be injured.
rundown - so what. We can charge it again in the morning if the kids forget to turn it off. Plus, the likelihood of running out of battery
overnight on our two-LED-light rig is pretty slim.
suffocation: First of all, we have an ice box, not a fridge
, so we don't have to worry about keeping it running. Second, no kid will fit in this thing.
Fire - A fire alarm is installed and the kids know how to open all windows
Sleepwalking - not an issue...so far.
Strangers - the kids are safer locked in the trailer than they would be on their own in the tent.
Best of luck!
