My advice would be to visit a dealer who has lots of different models in stock and to sit/lie/stand in them with all the people who will be in the pod with the door shut.  We did this at a dealership in Salem OR when we were looking and the experience really clarified what models we could and couldn't use.

Another possibility if the kids are big teens is to set them up on cots in the dome.  Although I've never spent the night in the dome, I have been known to nap in there from time to time.

If you're out west you most certainly end up with a HRE Rpod if you buy one.  But yes the east ones either do or can have added the same ground clearance for the most part.  There would be a tiny tiny tiny difference with the HRE's larger tires but that would be inconsequential.

Plenty of Pods can sleep 4 adults.  A 182g would come close to fitting what you're looking for as it has bunks and then a dinette which can be a queen bed.

But nothing has a queen standalone bed and bunks both.  A 178 has a queen bed and then a dinette that can be a bed at the opposite end and also would sleep 4.  

172 - biggest bunks, but least room as no slide out

176 - you get a slide out so more "hallway" space, but you lose some bunk width

182g - take a 176, flip the bunk with dinette, stick the garage on the back

as already mentioned, I'm not sure how teens would like the smaller bunks of the 176/182. I'd highly recommend going to see a dealer and looking at least at a 172 and 176. The 182 seems about the same inside as 176, just a garage on back. It's kind of a tradeoff of small bunks for a bit more hallway space.. hard to make a call there as 172 is pretty tight on the interior with just 2 adults. The other aspect is cost, as with anything more options means more cost.

For reference/opinion, i have a 172 and 2 small kids. The biggest challenge we run into is storage space, particularly for a longer trip, we tend to use about 1/3 of each bunk for clothes. That works when kids are little, teens would probably be more a challenge. We added numerous storage hanging pocket things, hooks, etc, but still have a hard time between the clothes/food.  Though you do get better and more efficient each trip .

We have 4 total in our 171, and when our kids got bigger I built a semi-permanent bunk above the dinette.  When camping we spend most of our time outside, even when raining, so we rarely have problems with space except right at bedtime (if the kids don't go to bed first, which they often do).  However, when touring (not camping) there are times when we are all in the pod for 10-12 hours at a time, like at truck stops, and then things feel tight at times - but really most of that time we are on the beds reading, on the net, or sleeping.

This is just a general statement of knowing and watched the "t" model owners over the years.  A lot of people are initially interested in them.  A lot of people like the thought of the hybrid feel so it feels like tent camping again, and then still others like the thought of the extra space and more room to sleep.

What ends up happening is the tent bed overhangs the dinette area a bit and is in the way for some owners, inevitably tents end up leaking (some owners haven't had this issue but more than a few have reported it; afterall it is a tent.  They are of course harder to heat and cool but that's not a huge issue.  The last thing I've seen owners complain about is just simply that it's a tent and requires more setup, if it's wet when you break camp you're going to have to pop the tent back out at home to let it dry etc.

I've seen owners love "t" models for the whole time they've owned them, but once they've moved on to something else they've commented they wouldn't own one again

When we bought it, I liked the tires and rims, my wife liked the frog..

What else defines the 'Hood River Edition'?
