Paste text at the end of the line with a space between in vim

Question

I'm trying to find a the fastest way to paste text at the end of the line, but with a space between the previous EOL and new text. The current method is a <ESC>p or o<ESC>pkJ. Is there any other, faster way to achive this? I'm thinking about something like "paste with offset"?

Original: The quick brown fox 
after $p: The quick brown foxjumps over the lazy dog
desired : The quick brown fox jumps over the lazy dog

If you do not want to use a mapping, you can type Aspacectrl+r".

See :h i_ctrl-r for more information. This is what is happening:

A        Append text to end of line (enters insert mode).
space  - Actual space key to insert a space.
ctrl+r - Insert contents of a register.
"      - Default register of yank and paste.
