We now have a 33' fifth wheel we tow with a newer 2015 3500 diesel. It is great for living space with a shorter towing length, but they cost $$$. Fifth wheels also cost more. I would suggest that your needs and wants will change over time. Start cheaper and stay within your budget for the next few years. You will be able to enjoy the experience more if you don't bite off more than you can chew! Kids cost money in ways you are just beginning to experience. You don't want to skip school clothes for a truck or trailer payment. Your days for a nice, big unit will come soon enough. Our kids never missed having a bigger trailer with more stuff. Now, they are grown and camp with their own families (so far, in tents).
