purchasing getting closer

Thanks for your returns. Couple of questions that I've seen in other places. 1. When responders refer to "stashes" or others say substantial accounts, in numbers, what does this mean? 5,10,15,20 grand for emergency needs. I believe in this but want experienced rvers for realistic amounts for planning. 2. As I have stated, we owned a 30' gasser for weekend, vacation and motorcycle racing 8 months of the year. Only traveled over the Smokies and towing. My question, numerous times people have said if not full timing get a gasser, I don't understand this if we really like diesel floorplans, no center entry door, larger kitchen, ride/noise level comfort, just plain bigger space. We plan to travel a month at once at least 4-6 times a year. Diesels just read and look like pure pleasure as long as one buys/inspects correctly. As stated, getting closer really brings up many concerns. If applicable to any unit, we will purchase a warranty. There is nothing like educated opinions from knowledgable people on a subject. The unit I referred to originally is on an R8 chassis, per internet sources. Thanks to all.
