I've never seen B30 at a car or truck filling station. Most, including Minnesota, label their diesel pumps B5 to maybe B20 and I doubt there has anything above B10 from information I've read. Mercedes Benz allows up to B20. They don't like it but it doesn't void any warranties. It definitely reduces miles per gallon averages.
This is one of the least of my worries and does not prevent me to have a fourth Class B built on the Mercedes Benz platform.
If you are traveling only with a spouse and no children I think the obvious choice is 24A with the fixed bed and ample room to turn around the driver's seat without a tall cabinet causing you to only turn around part way and have a feeling of claustrophobia. I suspect you can get way more storage under the fixed bed than the convertible sofa models.
I base my feelings having had a sofa/bed with ottomans and infills, a tri-fold sofa without infills and fixed beds with the notch to get in and successively more under bed storage. I have also successively had no driver's seat turn around, to a partial turn around facing a tall cabinet and a full turn around with a tall cabinet pulled back.
It is nicer to have all the tall cabinets and bathroom behind the driver so never in his line of sight. With the extra seats up front you can entertain guest but that would be rare. In a campsite unless it is raining you entertain outside. The extra space they take up takes away more practical space for other things.
The convertible sofa into a bed is nice when a sofa but you have to make a decision of bed or staying up. Riding on those sofa's is an adventure. We took grandkids twice on thousand mile trips and they have never asked again.
If you travel three or more or use your van other than camping such as for tailgating or every day then 24A would not be a choice.
When I was searching I rejected due to no propane stove.
I dry camp most of the time and electric burner cook top would not work for us.
I know this is an old post, but just wanted to say (in case someone finds this later like me), that there is a propane cock top option. Also, you could consider the lithium battery package (and now available with a second battery option) to make running the electric burner a non-issue.
Seems the Galleria would be a good fit for people that always camp with electric available.
I described my situation/use and I doubt the Galleria would handle that.I am sorry to harp on this, but that is just not true. We rented a Galleria for two weeks last summer and maybe hooked to electric three or four times at most, simply because it was there. We spent a number of days in a row without hooking up and were never short on battery power, and that was with an electric cook top and standard battery package. It had a generator that we tested for volume, but we actually never used it. Sure,if you completely block the 300 watts of solar, don't drive anywhere, and spend all your days cooking and using all kinds of power, then yeah, you are going to strain a basic battery system. But that seems like an extreme situation that most off-the-lot RVs would struggle with, so maybe seek out the propane cook top and/or the upgraded electrical package. To just declare that a unit it must ALWAYS be connected to electric simply because you assume it can't handle your unique situation is inappropriate and saying so is a disservice to others trying to research their next rig.
I described my situation/use and I doubt the Galleria would handle that.
I also camp for 10 days without moving in the fall.
Tell me a Galleria will handle cooking three meals a day and power the furnace blower along with lights and TV use. I rather doubt that.
I did no one a disservice by describing the difference between styles of camping and what may or may not work.
Drive every day and a Galleria may work ok.
Camp without moving for an extended time and I doubt a Galleria would handle that without running a generator.
I don't understand why I am getting so much flack for simply stating that the Galleria has a propane cook top as an option.
Juts so people know.
That's it.
Period.
End of my contribution.
Sorry for trying to be helpful. I guess i earned my lesson.
What model year were you renting?
