How do I pick the right RV for my family?

I cannot thank you all enough for your kind and honest words. This purchase is defenitly a process and one we are not taking lightly. I feel like I research a little more each and every day. We have pretty much settled on a MH as it is very important to my husband and kids that they be comfortable on the actual road trip. Fortunately my husbands Navy career has tought him to be a mechanic so the additional maintenance does not bother him. We have also decided that we will rent our MH to other military families to offset some of our costs. It's not an ideal situation but one that greatly appeals to us financially. As DH starts his transition back to civilian life (retirement in 2017) our plan is to use the MH for weekend trips and family vacations. Ultimately working up to the post Navy retirement summer on the road! We are currently looking at a Thor Windsport 34J model. As far as we can tell now, it has everything we are looking for and while a pricey purchase it is well within our budget as is the insurance, gas and CG fees etc. Have not signed the dotted line just yet but hopefully by this fall we can share pictures of our first adventure!
