Someone told me instead of renting a uhaul down south I should buy a trailer and resell it in AK and that would easily pay for my gas. True?

Is this a good idea? Are trailers in high demand up here? I’ll be traveling down to the lower 48 this summer and then back up and will be bringing some stuff back. If I could save money by not renting a uhaul and actually make some money on reselling a trailer that would be great. Is there a certain type of trailer that would sell very easily up here? Ill probably need a 7x12 enclosed trailer. I definitely do not want a trailer and want to make sure it sells easily. What’s the best trailer to sell easy and achieve this? Thank you In advance!
