For the OP, a question (or 2..or 3) to ask yourself....
How long do you plan to keep the tow vehicle/trailer combo? At some point, would you want to go to a bigger trailer, ie, as the family grows?
Family growth. Those kiddos under 5 years old now, will grow, and at some point, rapidly! And the stuff that they want to bring along will grow exponentially. Factor in perhaps a dog (please, daddy, can we get one...PLEASE???) and a bit more weight. Payload will be something to consider.
That Mallard M185 looks like a good floorplan for a family starting out. But after a while, you may want to consider a trailer with a slide out or 2 to give all of you a bit more breathing room.
Just throwing some other things to consider, so there are no surprises when you go to buy.
