Welcome from Georgia as well my friend!! As Helmsey said, check your weights and axles and read up on both the Sandpiper and Sierra forums. Especially these threads here 365saq weight ?
PLEASE do NOT let these threads scare you. Congrats on purchasing the best floor plan available for those of us with kids! Just give them a read. Also, you will want 2nd A/C unit for the rig too if it doesn't have one. This rig is awesome to pull and we love ours more each time we use it!
