Welcome to the world of camping with kids. It really is not as hard as people make out. You just need to be organised, but dont worry, you will still forget something on every trip.
My hubby and I have 2 kids, now 7 and 5 (+ 2 dogs) and took our daughter on her first camping trip at 6 weeks old. Our first CT was the fold out style with a box trailer underneath. Hubby recons that would be the best for you to tow as TAR weight is about 400kilo unloaded. (Panel beater so he should know). We had one with an awning and it was great.
It fitted 9 x 60 litre plastic containers perfectly underneath. I just put a hook on the end of my broom to pull the containers out. (Used one for us, one for linnen, one for the kids, 1 for kitchen stuff, 1 for food and the rest for other crap.
About the lights, we purchased a set of 4 of the outdoor solar lights, put them outside of a day time to charge, then put one at the foot of each childs bed, it gave off enough light to keep them happy. I also used to have a "wee bucket" for those 2am pit stops, and my kids soon became masters at doing the good old "bucket wee". BUT DONT KICK THE BUCKET OVER!!!!!!
We then upgraded to a Jayco Pop Top, but that would be too heavy as it has a tar weight of around 900kilo. That was great for our first big trip. We did from Central Coast of NSW up to Cooktown, far north QLD, then down through Charleville and the outback of NSW, then Dubbo then home. Total kms of 7,500 in 5 weeks. Kids were 2 and 4 yrs then. It was great. Highly recommended and eldest still remembers the trip.
Another trip we did was through the centre of Australia - a total of 11,000kms in 5 weeks. So worth it for the kids.
We upgraded again, and again, and now have a caravan that we will be taking 12 months off to go around Australia.
Kids love travelling so much that my son wanted to go to Broken Hill for his 5th birthday so we can go fossicking. (Only a 3 day trip).
A really nice place to stay with little kids is Swansea Gardens Caravan Park. (Bout 1 30mins from Wahroonga) There is a playground and pool at the park and is on the lake. It is very shallow at the edge of the lake and is no more than knee height for at lease 20 metres. Gives the kids a great place to play. Check out firstname.lastname@example.org
. Let me know if you want some more information bout it.
Waffled on enough. Take care. Nenie
Be happy - take the family camping.
