2016 Coachmen Mirada 35BH Gas VS 2010 Berkshire Diesel 39BH

Can understand your desire not to just spend $6k on a rental, but when you consider what you could lose on a purchase, it may not seem bad.
You didnt mention any experience with this as a travel method, nor have you mentioned past experience driving something of this size. You may find the travel part to be more nerve wracking than going to work, for both you and your family. A rental for a weekend trip or two would be my first suggestion to get an idea of whether this is a method you and your family can enjoy together.
Figure 300-400 miles a day for your travel time, confined in the size space youre considering, will your family be happy together? Do you have enough time available to throw in a couple of days off to let everyone unwind, maybe near a theme park or other venue.
It would have been great if you could have started this process a month ago to try that.
Happy motorin.

That's a lot of people in a RV. Check the CCC (not sure what it's called nowadays??)...cargo carrying capacity....all the people's weight, all of your stuff, food, fuel, water, etc. That's going to be a big determining factor on whatever you buy. Also, enough storage for all of your things should be looked at.

Thank you for the quick reply. We live in AZ and have a home rented in CT end of July. We were going to rent an RV but at $6K for 3 weeks, we started looking at ownership. We figure we could use the $6K as a deposit, and just own and get a lot more use out of it. The biggest issue is our budget around 80K and the features we want in an RV. ie: Bunkhouse, sleeping for 8 to 10 etc.. were found more with Gas coaches in the last 5 years. What we found was a lot of the older Diesel models, didn't have the bunk houses, and when you get below a 2004 model, the interior becomes too dated (wife factor). However, when we started looking at review sites, the Gas models came with lower quality materials and a lot of the reviews weren't very good. That is why I posted here. We found a Berkshire Diesel that we are going to look at in the next two days. However, we found a very clean coachmen Mirada that has all the features we like, but the reviews haven't been that good. There is just so much to learn about these vehicles, that is the reason for the post.

You likely don't realize you just poked the hornet's nest that is the ongoing, never ending gas V diesel debate that plagues forums. Better stick close and get what answers you can before it gets out of hand and the mods shut it down. Once that happens you might do a search and you'll find hundreds of threads with arguments and maybe even some good information sprinkled in to answer your question.
