but i never pulled my popups with it. i had underpowered TVs for pulling those.
for a mpg range, you should be between 9-12mpg. not going to be close to what pulling a popup is for gas mileage.
It could have just been the fact that I was pretty much going uphill the whole way back. I think I was getting about 6-8MPG. I got 14MPG average towing the pop-up.
Hit up camping world and walmart today for some accessories (mostly organizational supplies) and started outfitting the trailer with all the gear. It really does hold a lot of stuff.
Still on the list to get:
-Step ladder (I can barely reach the latches for the beds)
-sockets (one for the hot water heater, lug nuts, and jacks to hook into my power drill among other things)
-Streamlight "Fire Vulcan" rechargeable flashlight mounted near the door
-Garmin 1450LMT (time to upgrade my old GPS)
-level (dedicated to camper)
-carpeting for stairs
will be driveway camping later this week to fully test everything out.
