We have a similar toad and it rides on a trailer that looks a lot like yours.
We ride a red Yamaha Majesty scooter (469lbs) and carry it on a 4ft by 8ft Harbor Freight fold up trailer. The trailer tires have a max pressure of 60lbs for full load so I put in 50lbs just to be safe....wrong. After 8000 miles the center of the tread was bald. Now running 35lbs.
Love exploring on 2 wheels and the gas mileage is great. The trailer folds up when not in use and only takes up 2ft by 5ft in the garage.
Have a great time this Summer.
