How much will a big fifth wheel limit us?

First of all it will DEFINATELY affect your access to State and National Parks, COE, National forests and remote Boondocking areas. Go to their websites and try to reserve a site for that big a rig plus your truck. If you try this on several of these you will see that it will severely limit you. I'm not saying there won't be some but the Majority will not be able to accommodate you plus the parking when you do get in will be a nightmare. Also consider your slides and if you have access to all the areas you need to when you pull over to sleep at night and have to keep slides in. 5th wheels are very roomy with lots of storage for full time living but you need to shop carefully and balance what you WANT and what you NEED. We've had 3 5ers and it turns out the smallest (and first) was the best and most convenient. Larger in not necessarily better. Whatever you get just enjoy it while you are young!
