Seeing that I really know nothing about buses (yet), would it be safe to assume I could find a bus that stays under 2000 RPM at 60 MPH? If I could get around that, what are some key things I should be looking for? Excuse me, for I am no mechanic.. that might be a problem down the road, but I'll figure it out.

It'd help to have full sized tires. 11Rx22.5 are some of the most common. I think they're close to 40" diameter. My 10Rx22.5s are 38.5".

You also need a good axle ratio. The smaller the number the better. Mine is 4.33 and that's pretty good. A lot of people have 5+.

A couple of reference points:

Speeds at 2000 rpm (assuming 1:1 final gear ratio and 40" tires):

5.5 axle ratio: 43.3 mph
5 axle ratio: 47.6 mph
4.5 axle ratio: 52.9 mph
4 axle ratio: 59.5 mph

Overdrive would also help a fair amount.

so, I looked at the specs on the allison md3060 transmission.

the first overdrive gear is 0.75. the highest gear is 0.65. Given a 40" tire with the engine at 2000 rpm and an axle ratio of 5 that equates to a speed of 63.5 mph in 5th gear and 73.2 mph in 6th gear.

As I said, I don't mind living life in the slow lane. Back roads and <55MPH sounds like a decent life to me. Not to mention the savings in gas (where it would apply). Thanks for the info, I will be keep all that in mind when the time comes.

ah, a short bus vs larger bus question....
the way I'm going to approach is the way I look at toilet paper.

It's better to have toilet paper and not need it, than to need it and not have it!

Only you know of your size requirements and know what you can and cannot live with or without.
Although my 5 year plan is considering it will only be myself in the bus... I cannot say I'll be alone in 5 years.

personally, I'm searching for the larger 2ply Charmin.

We bought a propane RV stove/oven combo. Then we sold our propane RV stove/oven combo without every taking it from the house to the bus.

After reading here and finding out after the fact that Hubby does not want to deal with propane we ended up going with an induction burner and one of the NuWave ovens.

I have been using both in the house here since October of last year and I love them both. Neither put out very much heat and cook superfast. I turned my house stove into a countertop with tons of storage in the oven.

We got the rental bill a couple of months ago for our propane tank and because I don't want to renew it I tried to use up the 6% propane left in the tank so they can come & get it. I tried going back to the house stove and after about a month I said fu--rget it & told them to come & get it, gas and all.

I also like the idea of being able to store these away when I'm not cooking in a much smaller space than a stove would take up.

I had originally thought to use a 24 inch propane kitchen stove for heat & cooking as I had done in my first bus but I couldn't finding any that didn't cost an arm & a leg....and thinking back to how we installed it, it's surprising the fumes didn't kill us or blow us up. I guess the Universe is indeed watching out for us.

Did you opt against it, because of the fumes, and possibility of ignition? I have seen people using propane for years, and with proper care and ventilation, they have no problems. I am just curious why you decided not to use it. Obviously safety is my number 1 concern, but I am curious how much more solar components I will have to invest in, in order to run convection. I don't plan on having an oven (maybe some time in the future), so that should help.

I absolutely hear you. When I first came up with this crazy idea, I thought we would just be travelling around for extended periods of time. Considering I am going to have to quit my job, why would I want to come back, just to try to find another job? We might as well stay on the road. Who knows, maybe we find a spot we want to settle down in a year, in which case, some might say a larger bus might be over kill. At the same time, I figured if that time does come, we could continue to live out of the bus instead of going back to paying rent. The more time I spend on here, and the more I think about it, the bigger my envisioned bus is getting. I still would like to keep it on the smaller side for ease and simplicity, but I think a 30 passenger (I know they are referred to by interior size, which I think would be about 35'? But I am still learning, so I am not up with the lingo) would be perfect - small enough that she can feel comfortable driving, but big enough to live our lives in.
