Question: Can this heater be used safely in a small teardrop camper?
Document: The heater works just fine only I was suprised it didn't have a sparker. Once I got used to it there was no problem
Purchased used golf cart so husband could use until the snow flies but he was cold so purchased this heater and it fits in the cup holder and wow it kicks out the heat! Great buy!
The only reason I didn't give it 5 stars is because the cup holder doesn't fit snug enough. We bought it specifically for our golf car. It needs to be a little more secure fitting in the cupholder. Going over a big bump would possibly cause it to fall out of the cup holder so we keep a close eye on it. As were  driving around over some small bumps and through turns, the heater jiggles around a lot.
It has a small leak and I cant seem to fix it. How do I return it if I cant fix it
This would be great for camping or even in the garage when doing a small project. It is well made and does provide a level of comfort that winter would deny us.
Used this in the golf car this winter. It really takes off the chill early in the morning...Have the car enclosed so this is probably more  effective than if it were open. There are two choices for mounting, one for placing on the floor and then the one I have been using is the adaptor for the cup holder. The photo leads you to think this has a self-igniter, it does not.
This heater is a gem extending outings in our cart to even the frostiest days. Works just fine for the great price.
once I figured out that the directions that came with this heater were wrong, I was very pleased with it. The directions indicate this heater is electronic ignited but it is MANUAL.
The service and shipping was good, but the product was not as advertised. I ordered the heater thinking it was self igniting, but it required a match or lighter. I returned it.
This was a Christmas gift for my husband to use in his golf cart. The heater arrived on time, in exactly the condition advertised and my husband loves it!. I absolutely recommend this seller!
Answer: no
