The closest I can think of to a universal solution are the major chain truck stops.
Petro, Flying J, etc. They're used to receiving packages for truckers.  All the major
chains have web sites that show their locations along with phone numbers.  You have
to figure out where you're going to be, locate the appropriate truck stop, and phone
ahead.

The only other solution I can think of involves using those personal shipping stores
like what used to be known as "mailboxes etc.".  Again, you'd have to figure out
where you're going to be on a certain date, then call ahead and make arrangements.

When I was driving a semi over the road, I used the truck stop solution occasionally.
But since I pass by home every month or two, I had most of them delivered to a
business owned by a friend.

I'm going crazy. Wanna come along?

I ordered a part up in Gunnison, Co. and had it delivered to the local UPS
place in town.  Did just fine.

I have had trouble getting items shipped to an address other than the
billing address shown by my credit card company.  I am sure there is a
dollar purchase limit before they refuse to ship to other addresses, but
have got in the habit of calling the credit card company and changing my
billing address to wherever I am at the time and then change it back after
the item has been shipped.  As far as an on the road address, we use the RV
park where we are or will be when we expect the item to arrive.

I have stuff shipped to the billing address on our credit card, then
have our mailing service forward it along with the rest of our mail to
wherever we are.

I've ordered quite a few things online and had it delivered to an RV
park in AZ while my billing address is in MN.  Only one company has
called to verify my billing address phone number.

If you know the RV park where you will be staying, ask them if they will
accept your package. We had our medicines shipped by mail all during our
9 years of full timing and during our trips after that. DH has insulin
shipped and we've never had a problem as long as we asked first. The RV
park would even refrigerate the package for us. We've had things shipped
as much as 5 days before we expected to arrive.

Of course, one should make a reservation with the RV park first <g>

I once had a problem with the company not wanting to ship to an address
other than the billing address. It was not the shipper but the bank that
issues the credit card who objected. I called the bank and asked them to
allow the purchase to go through and they did.

I have also had things sent to General Delivery at the US Post office
but I first had to make sure they were shipping via postal service and
not UPS or Fed Ex.

I've had things shipped to a different than billing address before. Last
winter I had some plastic worms shipped to Florida, the vendor shipped
to New York then shipped me a new order in Florida. I've found most who
do this ask for the number on the back of the card. That way, someone
who has stolen your card number can't get stuff shipped to a different
address.
