Tier B · TL;DR
All-electric trailers fail because they steal the boondocking battery — fix it with onboard generation

Claim

Traditional travel trailers are heavy, un-aerodynamic bricks that destroy EV range. All-electric trailers try to fix this by using their battery to assist with towing, but that drains the power needed for actual off-grid camping, forcing customers back to crowded campsite hookups. Evotrex eliminates that compromise by integrating an ultra-efficient onboard power generator that automatically recharges the trailer's battery — seamless tow assist on the highway, limitless boondocking power off it.

Mechanism

The category's mistake is treating tow energy and camp energy as one battery. Splitting the energy budget by adding onboard generation means the tow load doesn't compete with the camping load, so the customer experience holds up across both jobs. That single design choice is the marketing wedge: it lets the product own a use case competitors can't replicate without rearchitecting.

Conditions

Holds for outdoor / RV categories where buyers care about both range and off-grid utility. Fails for urban-only EV use cases where off-grid power is irrelevant.
