My garage is 143in long and my 2014 ,900 rzr 4 fits ,not much room to spare.I also put a front bumber on and it will still go in.The back tires are on the incline still,but after I get it secure all is well.My bumber sticks out about 3 to 4 in.I think at 144in you are good to go!!!! the 1000 will not fit,that is why I bought one of the last 900's in AZ.Had to go to Cottonwood to get it , but I had bought my Ranger from them in 08.Been great so far ,put 143mi on it last weekend in Parks,and Sedona.Love Casner MTN!!!!
