Hey Damien, we've got the Trackabout Safari SV Extenda which has the walkway. SWMBO and I are in our early 50's and by no means fit nor nimble, but we have been tent camping most of our lives. Once we get the Trackie into position, we can get the main tent up with corners pegged down, which includes cover unzipped, corner legs down, walk through steps down, in no more than 10 minutes. If we then want the kitchen awning up with 4 spreaders, 4 poles and 4 ropes in another 10 to 15 minutes depending on if it's windy or raining. We find the sometimes most challenging part of set up selecting a site. This has been known to take 1/2hr:-)
We've only has one mouse get into the tent on the numerous occasions we've been out, and pretty sure it came through the doorway. Never had any trouble with bugs, grubs, nor spiders etc to date. We also love all the extra room we get as the tent area is bigger over the longer trailer base that includes the walkway. The kitchen awning is a great place for afternoon beer, wine and nibbles without needing to use the main sleeping area. We also have the Drifta pullout kitchen and Pantry drawer in the kitchen area and for the first time in all our years camping, swmbo is the one pestering me for "when's the next trip". The QS bed is also a winner with heaps of sleeping room, but here's something to consider. I get the centre side of the bed as swmbo was scared about falling off in the night, so she has the tent side of the bed. Our Trackie has a somewhat vertical tent side next to where she sleeps, but we saw many CT's had an angled side. SWMBO was concerned about feeling claustrophobic with the other brands as the angled tent wall came in on her sleeping side. The Trackie also has 4 large drawers that open into the walkway, so with the pantry drawer in the kitchen, we're always packed and ready to go, only needing to get fresh food.
Hope this helps.
