Hi Julie,
Since I don't live in an RV or know anyone that does, the shipping thing didn't occur to me. That's a good point.
BUT other than that I think this might be a really good one. Especially if you are interested and have experience with the topic.
The main thing I see is that RVing appeals to boomers who are a very lucrative market. And I think I'm seeing some good search volume and relatively low competition. (
after admittedly just a quick look and not in-depth research)
I scanned for RV affiliate program not expecting to find much and there is quite a lot that looks interesting.
RV affiliate program - Google Search
I scanned Wordtracker for RV keywords and for some reason RV furniture looked good to me.
Checked the competition and it looks fairly reasonable. allintitle: "RV furniture"
allintitle: "RV furniture" - Google Search
Here's a merchant that brags they sell "all things RV" including RV furniture and even RVs.
And they have an affiliate program.
RV Supplies, RV Accessories & RV Parts - Camping World
The other thing I like about this market is - even thought the PRODUCT NICHE you are looking at is RV owners, the demographic is really Boomers and seniors. So you focus on the RV owners and get into the niche, but then you can sell anything non RV too that would appeal to seniors - like health and nutrition products for example.
Sorry, really tired, so those are just some really quick thoughts. But I definitely think it could be a good one for you.
