Check out an Outfitter Juno 8. Your truck can handle it and it has a tent room for the dogs (or grandkids). The tent room easily fits our two st bernards and our four year old son with room to spare. We have the Juno 10 with a four year old, two adults and two 160 lb dogs. Space is still at a premium but that tent room with dogs and kids is a life saver. Cannot stress that enough. We had a 10' camper with a full wall slide and this camper feels more spacious because we're not shuffling around dogs and kids constantly.
Other pluses: Fuel mileage and handling with the popup vs hard side is great. The newer, I think 2013-14 models and newer, are solid fiberglass bodies and one piece fiberglass roof. The dinette seats are a slightly reclining angle, no idea why other manufacturers haven't caught on to this. Plenty of storage under the bed and around the camper. Wet bath. 400 ah of batteries. Heated basement with a return vent in the basement as well, vs just pumping in heat like some others. Side entry.
Downsides. Slightly colder than our hardside but we've still camped down to zero degrees with a -20 windchill and been a cozy 67 inside. Noise is more noticeable than our well insulated hardside, not terribly so but it's a noticeable difference. Have to put the top up and down and fold up the tent room to get up and go.
