What they said.
Do a lot of research.
I've seen diesel pushers go for $3500 before the economic collapse.
I have my eye on an older interstate bus, $1000 or scrap value, negotiable.
All aluminum and diesel.
If options aren't exactly what you want, they add no value at all.
A rebuilt engine lowers market value, not raises it.
You may find it more desirable, but look carefully.
I have a car with a factory rebuilt engine and they did everything wrong you could do, without causing mechanical damage.
All kinds of fittings missing, which turn out to be essential for something.
Only hotrods go up in value with engine work, and the buyers get pickier.
Get the trailer life technical books first.
Hire an expert to negotiate for you and advise you.
Even an enthusiast.
Go for a steel or aluminum frame vehicle always, or pay giveaway prices only.
RVs range from free to millions of dollars.
The high end are based on upgraded interstate bus chassis from europe, with suspensions as sophisticated as any sports or luxury vehicle.
Also note that any vehicle can be improved dramatically with antisway bar upgrades and minor suspension tweaks.
IPD is one source.
Can reduce stress and make driving a pleasure or save your life, depending.
Worth noting that some generator enclosures are extremely sophisticated and add considerably to the noise reduction and access.
Also, met an ac tech.
He says new high end window units, and maybe rooftop units?, are using many tricks to improve efficiency a great deal.
Can go into more detail, but much lower power drain, shorter life.
I am going to run the numbers to see if it's worth getting a new unit over the ones I have, just for electric savings.
Much faster payoff with off grid use.
Likely not the case with $100 throwaways from walmart.
The reduction from a top end older unit may be almost half power use.
My theory is that used with low loads and high ventilation use, the older ones are better than the ratings, but we'll see.
For an rv, I think the newer ones will be better.
Also depends on the amount of use you plan, and type.
Consider upgrading lighting, and consider solar if use will be enough to justify it.
