>>1097060What country are you in? The most popular length travel trailer sold in the USA is a "28ft" bunkhouse, which is about 31ft long with the hitch. Even my travel trailer, which is considered small by some standards, is a "26ft" model, and is about 29ft with the hitch.
Also, you'd be amazed how much weight you pack in an RV. Coolers full of drinks, bikes for each of the 6 people, a portable grill, cookware, clothes, toys for kids, ect ect. It adds up. That's not counting extra chairs you bring, firewood you pack in as well. It's basically the complete opposite of backpacking.
I have an RV and I also backpack, 2 complete opposite philosophies of camping, both equally as fun.
