I bought a Snopro 7.5 X 16' a couple years ago. It was built with extra height for a side by side. Tows nicely and can fit two sleds on a deck with plenty of clearance. The only thing I would change is bigger axles. The trailer comes with dinky 2200lb axles.
When I first fired mine the pump was struggling to get the fuel all the way to the heater before the heater would time out and throw an error code. I used the air compressor and pressurized the fuel tank while the pump was running to get the fuel all the way to the heater. Hasn't been a problem...
Make sure your fuel line is the rigid white plastic line. The fuel pump is a pulse style pump. It will not work well if the fuel line is not rigid. My fuel tank is outside my trailer on the tongue and I am pumping the fuel 8' away and 4' up to the heater. Pump is mounted just outside the fuel tank.
Like others Smith Goggles have been really good for me. Pricey though.
Have a couple of the ZEAL portals. They do let snow in when you have dry powder. Snow gets between the frame and lense. Always found small amounts of snow on the inside of the goggle.
Found a cheaper goggle a couple years...
This chassis is about 5 years to late. Cat is playing catch up now and doing a poor job at it. I read somewhere that the sled at haydays didn't have an engine in it and they wouldn't open the panels. LOL.
Depends on your rim size, we have been running Toyo M55's on our crew trucks for a few years now. They don't come in anything bigger than 18" though.
