A new member is planning to build a square drop camper on a utility trailer base, inspired by memories of camping with his late father. He’s considering whether to stick with a 4x8 base or go larger, given his 1500lb towing capacity. Several experienced RVers weigh in: those who built 4x8 models say they’re manageable for solo camping and easier to store, but most recommend a 5x8 or even 5x10 if he plans to sleep two adults, citing the significant comfort difference. The extra width not only... More...

Howdy! Im getting ready to start my build. Been researching for a few weeks now and have decided im going to build my own square drop from a utility trailer base.

I’m 25 M, my pops and I used to camp but he unfortunately passed from ALS complications in December. I’m changing careers and becoming a teacher, like him. We always wanted to see the country together, and I think this would be a great way to spend my new summers off! (Gotta make the pay cut worth it lol)

I started off thinking I’d build 4x8 base but now I’m thinking about going a little bigger… right now I have 1500lb towing capacity to haul it with so I’m worried about weight mostly…
What do you think? Should/could I go bigger than 4x8?

Thanks look forward to seeing all the old build threads!
 
I recently completed my first square drop built on a 4x8 trailer on 4x8 Harbor Freight frame. After building and sleeping it, I regret not building a 5x8 trailer on a 5x8 northern tool bolt together frame. That extra foot in width is definitely usable living space if you ever plan to sleep 2 adults. 4x8 is doable if you don't mind bumping up against someone else.

For off road, the extra width would provide additional stability. Also, tracks better to the tow vehicle. Hard to pick a line over deeper ruts.

The 4x8 does make for a simpler square drop build, takes up less space in the garage, and with very little wood or foam waste in 4x8 sheets.

Have fun.
 
I built a little 4 x 8' for my sis. It weighs under a thousand.

Our 5x10' weighs 1340 empty.

By the way, a lot of builders on here will argue that the classical teardrop shape is easier (and stronger) than an angled build.
