I've been living full-time in an RV off and on for nearly a decade. I just bought my third RV (first was a motorhome, second was a travel trailer, which I had for three years and grew to hate moving it, and now I'm back to another motorhome...motorhomes are just better if you travel a lot) and I'll be traveling pretty seriously again for the next year or so.
Relationships suffer, for sure. I've always been a hardcore loner, and I'm mostly OK with that. I can make friends, and I don't have trouble dating, and I often do when I stay somewhere for more than a couple of months. But, realistically, I'm not good at maintaining relationships, and traveling a lot exacerbates that a lot. Traveling isn't the only factor in this, and it was true even before I started traveling. I'd get into a project or whatever and kinda forget about the rest of the world and the other people in it, sometimes for months at a time. I've been trying to alter this behavior somewhat, as I get older and recognize that real friendships come harder and harder every year.
So..yes. It can be quite lonely in practice. If you don't value alone time very highly, it might be too much. It doesn't have to be lonely, though. Being a traveler is interesting to a lot of people, so if you're at all socially proficient you can make new friends (or romantic partners, if you aren't already satisfied in that area) relatively easily, as long as you do social stuff while traveling (I do social bike rides, tech events, activism, and art/music stuff, when I have social energy to spend). They will probably be fleeting relationships, however. It's pretty rare that I meet someone in my travels that I keep in touch with forever.
Also, as much as I hate facebook and what it's been used for (and is being used for), it is nice to be able to connect up with people that way, since it makes it possible to run into people again later, maybe not even in the same city you met them in. Getting a cell number or email address just means I might contact them if I am back in the city I last saw them in; but with facebook, I might see that someone I know has moved to a city I'm going to, or whatever. It's sort of a live view of who I know, and that's really valuable. Sometimes, those old friends and acquaintances are happy to see me again, and that's nice.
