Strongest build Jayco Outback Finch & Doves were built between 2002-2005.
We had a 02 OB Finch which I think would be big enough for your family and small enough to get around in.

Like any camper, mod's are limited to your finances but there are a few relatively cheap ones that will make life in the Finch or Dove more pleasant.
These are my pro's & Con's but some may have different views
My Con's
with the Jayco pop ups is you cant access stove, sink or fridge unless set up. Hard floors generally have pull out kitchens. Some do modify pop ups with a slide out kitchen.
East/West bed for couples are not my favourite, ok for singles.
All though there are plenty of cupboards, there is limited usable space in them.
You must dust proof these campers.
My Pro's
Swinging entry door
Can cook inside but only in bad weather
Roof vent
Table, chairs & lounge which turns into a single bed.
Higher ground clearance
Safety bed nets, stop the little ones falling out.
Easy to insulate bed ends from the cold with portable insulation
The OB Finch is approx 1000kgs when loaded
These are just a few that we found.
